This is a good chance for someone to ease into liquipedia too.

Hrm, you should add this to liquipedia

just a thought, it would be nice to have some equeation that takes into account constant growing energy on the nexus, so say you were wanting to save chronoboost to get your collosus out as quick as possible in the game, it takes 3 full chronoboosts, however when you begin chronoboosting the robotics facility your nexus begins to gain energy and so you might only need to have 2 chronoboosts on your nexus because the third chronoboost will come from the energy gained during the first 2 chronoboost durations

Specifically you need:

3*25 - 0.5625(2*20) = 52.5 energy.

Which I guess you could generalize slightly as:

25N - 11.25(N-1)

but only works when N is an element of {2, 3, 4, 5, 6} and one nexus

which I guess I could just list out:

• 2 -> 38.75 (39)
  
• 3 -> 52.5 (53)
  
• 4 -> 62.25 (63)
  
• 5 -> 80
  
• 6 -> 93.75 (94)
  

FWIW this chronoboost math and energy regeneration is also why

- if you're getting psi storm you should build high templar just after you start your second chrono boost if your playing perfectly to have storms available when storm research finishes. (i.e. you want to warp in high templar at 37 ticks into storm reserach).

- if your early game split, probe stacking, and first pylon are done correctly you should chronoboost your nexus at 39 energy and again at 25 energy as a 9 pylon finishes just as your 10th probe chrono'd at 39 energy completes and your nexus gets 25 energy just as your first chronoboost wears out

No offence, but this is completely obvious. One chronoboost completes 30 seconds worth of build time in 20 seconds, so the time saving is 10 seconds.

Yes, maybe it is quite obvious if you look at the simplest line of the post and stop reading, but is it really THAT obvious that you need exactly 63energy saved when you need 4 chrono boosts back to back for an upgrade?

Maybe the OP isn't the most complex ever, but the discussion generated from this thread brought some really interesting information. Even I, as a low diamond protoss, had no clue that it took 45secs to get 25energy on my nexus, or that I needed 5 chrono boosts but only 80energy saved to get my warp gates research the fastest possible.

So yeah, maybe the first formula and explanations are a bit too complex for something so obvious to you, but it gave birth to a discussion a lot more useful than your post stating that it is obvious information.

I'm not the best player, and by far, but I know that at least it was useful to me, so it will probably be useful to a lot more people.

understanding this actually makes seem Chronoboost a pretty weak ability.

The strengh of CB is the reduction in buildtime thus (using ressources faster)
i.e. a Chronoboost on Probes is usually more "worth" it as a chronoboost Upgrades

upgrades get faster 160->150 thats not even 10% faster
while Probes get ofcourse alot faster build (i.e 2 probes take 34s, with CB its 24s)
thats nearly 1/3 reduction.

Same for Chronoboosting units if we take a Warpgate Zealot
takes 28s cooldown
with chronoboost it takes 18,666s
effectivly you would need 3 Chronocycles to make the Macromechanic "worth" an additional Zealot. (for longer buildtimes this gets even worse)

Now compare this to Mules:
1 Mule gets you ~270 thats nearly 2 Gateways/Rax
2 mules are 1 additional Nexus/CC
which boost you production capacity alot faster than chronoboost ever could
and it is ofcourse more forgiving cause it gives you minerals which makes you a hell of more flexible in what you want to spend it too.

This also shows why Protoss is hit hardest by Economic Harass, beeing able to boost production doesn't mean shit if you don't have the income to do that.

weakest Macromechanic (= on Economic side)

just to make a comparison:
a Terran who builds an CC in his base can produces (has the additional mules)
2 SCV in 17s
a Protoss who boosts his Probes gets:
2 Probes in 24s

This also shows how bad CB Scales when the counts of bases get higher.
How often do we see Progamers still having much much energy on their Nexuses during mid/late game.

Conclusion:
Using Chronoboost on things that have small buildtimes more effective than cause the Speedup in % is alot higher, than on slower buildtimes.

We will see Terrans do inbase CCs because of macromechanic
We will see Zergs do inbase Hatches because of macromechanic
We will never see Protoss do inbase Nexuses, because of macromechanic

I haven't read the thread yet, but is there a way to calculate the exact starting amount of energy required in order to chrono boost out warp-gate tech through the entire build time?
