Today i was looking a ZvZ replay form GousCup RO16, more precisely i was looking the third game between Kuroky and Orly game.
Orly opened with a 9 overlord while kuroki opened with a 10 overlord build. These are the results
Orly on the left Kuroki on the right (of the three drones orly was producing 1 had the same progress bar of kuroki) As you can clearly seen making the overlord at 9 gives you two faster drones giving no damage at all at your initial economy. So it makes no sense at all producing overlord at 10 instead that at 9.
|
Have you seen these results in other games or just this one?
Note the larva spawn positions compared to the minerals...
|
well i noticed that Orly tends to getting his ol at 9 every game... dont know what he is trying to accomplish with that though... A little research would very much be appreciated :D
|
No damage at all? Except for having one less drone for 20 seconds?
The 2 drones he gets out faster might be able to make up for it, but I doubt it. It'll probably be close.

I thought everyone now does 9 overlord or 10 with gas trick. Don't know about the gas trick but 9 is a tick faster than 10, as this example shows.
Edit: wasn't there a thread with actual income numbers comparing 9 against 10? Should read this forum more often....

would be interesting to see if it is the overlord or larva positioning o_o
|
Why was it 9ol in SCBW anyway? I wondered all the time why terran went 8or9/10 depot, protoss 8/9 pyl and only zerg made 9/9, waiting for the cap..

9o gets the 10th drone ~12 seconds later because that is the time it takes to harvest the additional 100 minerals required for an overlord. You are not limited in larvae at this time. So with the 1 mineral per second rule that means -12 minerals for 9o.
10o gets the drones 11, 12 and 13 about 6 seconds later because the ovelord is delayed by 50 minerals or 6 seconds compared to 9o. That results in -18 minerals at the time of drone spawn. This assumes that 9o has enough minerals and larvae to make 3 drones right as the overlord spawns. But findings from a single test run are that you don't have the minerals and larvae to make a third drone right away with 9o. It comes about 6 seconds later, which would result in 9o = 10o.
So the difference depends on very small details. Since 10o + extractor is slightly better than 10o, I would assume that 10o+e is at least as good as 9o.

I don't claim I ever intentionally tested this but if I am not completely stupid I always have enough minerals to make the 3rd drone right as the larvae spawns. Messed up split on his 1 test?
So who has a couple of minutes and an excel sheet and wants to break this down once and for all?

hmm the problem is not how faster it is (i think 3 seconds) but the minerals mined in the same time (normally when you have 14 drones), i mean, yeah i can have 14 drones and you 14 3 seconds late but you have 30 minerals more, in that case it's not worth it
|
I think that if you can have 30 minerals for free why don't claim them? :|

I mean if with 9 ovie at (hypothetically) 1:30 you have 14 drones and x minerals, its not woth it if 10 ovie at 1:30 (again hypotheticall) have your 14 probes and x+30 minerals, all of this should be tested at 14 drones to see the econ diference and choose which one is better

Considering the base positions I don't think that this one game shows anything. Kuroki's drones had to travel all the way around the hatchery until they could start mining. I can't quantify the impact precisely, but it could easily be the cause for the discrepancy. The choice of which mineral patch to harvest also plays a little role. 2 drones on a patch close to the hatch yield more income than one drone on a close patch and one on a far patch.

I've tried them both a fair bit.
10o will pause larva production while you sit at 3 larvae waiting for your OL to pop. Doing 9o will not. Doing 10o with the extractor trick will not.
Assuming you never sit at 3 larva, whether by using extractor trick, or 9o, your 14th drone is going to come at the exact same time. Any time you sit at 3 larva you're going to fall behind.
Going 10o extrick will lose you a few seconds of mining time, and drop you down by 1 mineral. A 1 mineral drop is really as impacting as a 5 mineral drop, as any costs are in 5 mineral multiples.
Going 9o will delay your 10th drone by some seconds (5-6 iirc), but it will also bring your 12th drone out earlier. I have never had an issue having enough minerals to get my 13th drone. Also, the larva for the 13th drone should not be spawned until after the overlord pops. If it has spawned, then you'd be sitting on 3 larva, losing larva time, and you probably waited to long to start morphing your overlord.
The whole idea is to never sit on 3 larva for more than a millisecond, or else you're delaying the next larva spawn.
By the 14th drone you should be in sync again, you should have no larva doing it either way. In terms of drone production, if they are both done properly, they should be identical.
In terms of mineral count, I've found I get better results with 9o, but that's variable based on your mineral patch locations, how you split your drones, how well you execute your extractor trick, etc. I find 9o is more reliable in any case, but that's just with my play. I'd not be surprised if someone with better mechanics can eek more out with the extrick.
One thing I'd like to know is whether maybe one order is better when your mineral patch is north of your base, while another is better when your patch is to the south.

9OL means your 10th drone mines for a smaller amount of time.
10th OL means your 11th and 12th drone mine for a longer amount of time. It also means you don't waste larvae because you aren't waiting with 3 larvae.
Therefore, 9OL must be better.

The builds in question should be 9 over and 10 over + extractor trick anyways. And you completely ignore the length of the time periods in question.

@ bongjwa: cus overlords took so much longer to build in BWit was better to just get your 9th first. think about the extreme, if overlord took 5 minutes to build in bw woldnt it make sense to get drone first
|
I remember testie making a post saying oldschool sc'ers proved that 8/9 ovi>9/9 ovi in sc1, but it never caught on. Not entirely sure though.
|
10ov is clearly suboptimal. 9ov and 10ov +extractor are very close to each other. Close enough that it'll be hard to prove the superiority of one over the other. Honestly, it may well boil down to personal preference.
