However, (and please correct me if I'm wrong), you could support 4.5 gateways worth of zealot sentry assuming you're not building probes or other stuff and are loosing units fast enough that pylons are unnecessary. So if the value that can be supported is more than 4 but less than 5, building 5 doesn't seem unreasonable. That is only if you don't have to build pylons or ... anything else... ever, so perhaps a situation where you smash the same 5 units into the the enemy each production cycle with all dying... that doesn't sound good again, there is nothing wrong with accepting that you macro is not perfect and you want to make up for it. or perhaps some situtational fun. Just understand what you're doing. as zerg I happly make extra hatch in base if I am falling behiend. It's important to know what is optimal, it's also equally important to know when not to go 'optimal' | ||

I'm trying not to be rude here. becase that concept doesn't really work other races... at least not in the same sense... The point made eariler in a very informative fashion was that you can't support 4-5 gate without cutting probes, and even pylons. Terran and toss are bottlenecked at 1 maybe 2 worker at a time... which is 3 min per sec... what do you do with the rest, stock pile it until he pushes out? and hope you have as many warpgates as he has units? I'm not even going to say anything more | ||

Besides that, having production buildings that you're not using 90-100% of the time is bad macro, period. But on to the point of this thread, there is no possible way to support 5 gateways, 4 gateways constantly being produced out of (and chronoboosted because, what else you using it on?) will take pretty much all your money. | ||

You are comparing a 4 gate allin to a saturated 5 gate allin off dts. Did you not consider that JMC may have pooled extra resources from his dt harass and could possibly sustain a 5 gateway production for 2 rounds? It may not seem like it would matter but 4 vs 5 stalkers can lose u games in pvp. Personally I think 5 gate has a place in PVX because its works as a adhoc substitute for the 4 gate allin with chrono boost saved for cranking out lots of units. Anyways I guess you already kind of understood this. | ||

Also, the extra gate wont be a waste as well, especially when you expand, you have to get the extra production facilities anyway. The gate is kind of like an insurance policy to hold early pushes. Edit: In context to the thread here, the additional production facilities, allows the toss to have extra units at a particular point in time - though its unsustainable for an extended period of time, it is very useful for certain timing attacks, to have a temporarily inflated army count to exploit certain periods of weakness in the opponent's build. | ||

When Day9 asks about this, he said that its essential to have the extra gate if he gets put under pressure, he can cut probes and pylons , chrono boost off all his production structures and warp in an extra 3-4 units which could be critical to holding off early game pushes.

I was going to bring up a similar point. Sometimes an extra gate can be useful if you're trying to NOT do an all-in, as it lets you defend if they all-in first more effectively. The cool thing about Warp Gates is that you really don't need to be producing out of them at all times nearly as much as Terran players do, as they still have worth even when a unit isn't being built. It's kind of similar to stockpiling larvae to build a response to an attack as Zerg. Perhaps a fast expand or fast Twilight Council with delayed Warp Gate would benefit from 5gating. I'm not sure how cost-effective it would be for an all-in, though. Seeing as it costs you very little, I wouldn't be opposed to testing it. | ||

I would assume with the 4 gate the moment the cooldowns expire you have achieved the necessary resources to fund 4 units. (off 2 gas and your minerals this will most likely be sentry and zealot heavy) But say the next warp cycle you are warping 3 sentries and 1 zealot that is 250/300/8. When you collect resources you dont jump from 0 to 300 instantly it is gradually taken in over time. So the cooldown on the 5th gate we be able to warp in a unit with these minerals that have not quite reached the 250/300 mark earlier. Why not just wait for the cooldowns to expire then warp in 4 units? There could be a dozen reasons say your 4 gate army has pushed out you just warped in 4 units at your proxy pylon and you see a bunch of enemy units nearby your base with a scout attempting to do a runby and kill some probes or infrastructure or something else. You can't warp in a sentry to block that ramp because you just warped in 4 units to do a push. O wait you can because you have the exta warpgate that is ready to go. | ||

You should always have a plan ready for "he's doing a run by!", so having a fifth gate to warp in a unit that should already be there is a waste. | ||

I'd like to add that, under some circumstances, it may be possible to support more than four gateways off of 1 base, but less than 5. Not using chronoboosts and doing away with silly notions such as integers, here's my take: + Show Spoiler + Note: Those numbers are parallel gates making units. With making pylons and with making probes, you can support a constant 1.795 zealots, 0.000 stalkers 1.216 sentries 3.011 (total) With making pylons and without making probes, you can support a constant 2.408 zealots, -0.000 stalkers 1.216 sentries 3.624 (total) Without making pylons and without making probes, you can support a constant 3.276 zealots, -0.000 stalkers 1.216 sentries 4.492 (total) Points to note: * Stalkers are more expensive then zealot/sentry. * 3 Gates is enough if you do not miss a step. You should have very little left over. * 4 Gate should be an all-in. You cannot support making probes and running 4 gates. * 5 Gates is for when you expect not to be making pylons or probes. They will still be a bit inactive. There's a fringe case: + Show Spoiler + Without making pylons and with making probes, you can support a constant 2.716 zealots, -0.000 stalkers 1.216 sentries 3.932 (total) I can't think of very common situation where you would be making probes and units, but no pylons.

On October 22 2010 10:20 ltortoise wrote: This is depressingly simple. Allow me to explain how with 15 paragraphs. (thank you eckm!) No, you can't support five gateways off of 1 base. Let's do some math, shall we? Maybe we will learn something from it. A saturated Protoss base (24 probes on 8 mineral patches, and 6 probes on 2 geysers) gets 13.6 minerals per second, and 3.8 gas per second. Now let's look at what a unit costs to produce continuously. We will disregard HT's and DT's because obviously they will be more expensive. We will also disregard chrono boost because that would make things worse. We seek only a combination of units that we can continuously produce off of 5 gateways, with all gateways in continuous usage. (there is some rounding but it should be good enough for you people. anybody who could appreciate the difference would never think that 5 gates could be supported anyway) A Zealot costs 100 minerals and has a 28 second warp gate cooldown. So a Zealot costs 3.57 minerals per second. Similarly, a Stalker costs 3.9 minerals per second and 1.56 gas per second. Sentry is 1.56 minerals per second and 3.125 gas per second. There is no combination of 5 of these units such that your minerals will stay below 13.6 per second and your gas will stay below 3.8 per second. Proof: It is easy to see that some number of Sentries will be required, since 5 zealots would cost 17.85 minerals per second, and stalkers cost more minerals per second than zealots. You can have at most 1.216 warp gates producing sentries due to gas restrictions (3.8 / 3.125). Assume this is the case. Thus, you need 3.784 warpgates producing Zealot/Stalker. The sentries leave you with 11.7 minerals per second. However, constant Zealot production out of the remaining 3.784 warpgates would equate to 13.51 minerals per second (we're assuming zealots since they are cheaper than stalkers in terms of minerals per second). Notice that decreasing the amount of sentries produced would increase the mineral cost further, since Sentries have the cheapest mineral/min. Thus, we have a contradiction since the 3.784 warpgates of zealot production + the 1.216 warpgates of sentry production put us at 15.4 minerals per second. QED. And this is extremely generous, too. I'm not even including pylon construction or probe construction! JUST the units! Edit: I forgot to answer the OP's question. If you can't support 5 gateways off 1 base, why do good players and even professionals sometimes do it? Answer: Because even professionals and good players slip up on macro. To spend all their money, they will need more gateways than they can support. Once they drop back down to low money, they will end up with a useless gateway unless they expanded. Great post. Although there is another way to look at it. If you don't have perfect macro, then you can take advantage of this 5 gate to catch up with your all in. Secondly, you can definitely utilize all the warpgates, but probably with an idle warpgate some of the time. | ||

It's quite of an all-in but with warpgate tech and if times goes by maybe charge it can demolish any early ground units besides banelings so if you encounter the zerg before he's teching Lair > Spire, your rather fine imo. | ||

-You're fully saturated -You're not making probes -You're losing units thus not making pylons -You're allowing some times in between warps (macro slips) This is all-in play. It's acceptable when you know your opponent expanded faster than you and you know it'll be hard to catch up. | ||

1) It is possible that you are floating minerals/gas waiting for warp-tech to finish. 2) In case you are under attack you will be able to reinforce quicker if you are losing your army (meaning no pylons and no probes). 3) Warping in one round of zealots (if for example he is pushing hard with zerglings) gives an abundance of gas, having a 5th gateway means that if you have 450 minerals and 150 gas you can get a sentry on top of the zealots. You could argue that you should not have 450 minerals in the first place but i see many protoss trying to float enough minerals for one round of warpin when they are pushing in order to reinforce with exactly the unit they need. Actually I do aswell in some games even on defence. Banking enough resources for one round units is not always bad, this means you can warp in exactly what you need to fend off whatever he is throwing at you, but on the other hand you will lack some units while they warp in, a FF on the ramp should buy you plenty of time. | ||
