I wrote a thread similar to this a few months ago that discusses the actual economic cost of chrono-ing something other than your Nexus early game and when. http://www.teamliquid.net/forum/viewmessage.php?topic_id=179604 I would be interested to see a cost-benefit analysis of using Chrono on units vs warp gates, but I might just write one up if I ever get around to thinking about it. Also it's worth noting that you should replace 33.3333% with 50% almost everywhere you note it. If something is supposed to take 9 seconds but only takes 6, it is 50% faster than expected. If it is 100% faster, then it is only 4.5 seconds, and if it is 200% faster it is only 2.25 seconds. 900% faster, it would be 1 second. Similarly, if something should take 9 seconds but is 33.33% faster, then it takes 6.75 seconds. Example: I want to chronoboost one probe. It builds in 11.5 seconds instead of 17. 17/11.5 = 1.5, or 50% faster. To compare 11.5 seconds to 17 seconds, we can say that it takes 67% as much time, or 33% less time, but we cannot say it is 33.33% faster. It is 50% faster. Lastly, if you give two letters do a variable, do not capitalize them both. (This is nitpicky, but CR should be Cr or just C, as CR implies C*R, two variables.) Hope this helps and thanks for the nifty spreadsheet. Gee thanks. You're right it's 50% faster. | ||

Good job for the dedication. Side Note: I also found out chrono boost speeds up warp gate transformation time lol | ||

 While we're discussing about Chronoboost, is there a thread talking about diminishing returns of chronoboost on probes ? (using chronoboost on your first probe is more effective for your economy than chronoboosting the second etc... and by how much). | ||

"Located at the Nexus, this ability can be activated using 25 energy and is used to increase the production or research speed at the target building by 50%. This allows the building to do 30 seconds of work in 20 seconds, so production/research will complete 10 seconds earlier." [/b]Diamond/Master level players are not the only people reading this. So this is useful information for a new person to Sc2 and/or the lower leagues. | ||

Never knew that chronoboost speeds up shield regen either. | ||

General Build Time formula If you apply more than one CB, then of course you get linear results: Two chronos= 20 seconds. Three chronos = 30 seconds. And so on. So the general formula to get a Bt modified by CB is: Bt'=Bt-N*Cr where N is the number of chronos applied. That formula doesn't work. An Immortal takes between 55.666-55.733 seconds to build (on normal speed). Normal doesn't follow the listed build times exactly. I used a frame-by-frame procedure of a recording of a digital stopwatch next to a robo, so there is no human error. If we use one chrono boost, it reduces the build time to between 45.300-45.367 seconds. So that chrono boost cut 10.366 seconds off the build time (on both sides) If we build another Immortal and instead use 2 chrono boosts, it cuts the time down to between 37.865-37.934, meaning the second chrono boost cut between 7.433-7.435 seconds off, for a total reduction of between 17.799-17.801 seconds. Following your formula, Bt' = Bt - N * Cr Bt' = 55.666 - 2 * 10.366 Bt' = 55.666 - 20.732 Bt' = 34.934 But the actual build time is 37.865-37.934 Or you could just break it by entering a worker unit into the formula (of which a CB cuts the time from 17.068-17.133 to 11.400-11.467, whereas the formula says ~7 seconds) About 5 months ago, I actually had started a big project regarding Chrono Boost and build times in regards to game speed and real time, but I lost 9-12 hours of research in a computer crash and didn't want to redo everything. | ||

Does Starcraft take different times to build something? Or is it that your measuring method can't be exact? I did all testing at fastest. Apparently on normal, 1 game second=1 real second but not sure how exact that can be. Also, CB Probe time is 11.33 (17/1.5), careful. I'd explain your findings this way: 1) Since you have to manually chrono boost ,there's some limit on how accurate you can be.You have to deal with human error (unless you're Jaedong, there's some reaction time delay). 2) Starcraft (in fact: a computer) is not exactly an "atomic clock". 3) Your measure method might not be exact enough. These factors add number noise. Most of the numbers you point out only differ in around 1% which I think is not really significant. | ||
