These histograms show the research time for various upgrades in Legacy of the Void. The data comes from ~2200 replays uploaded to http://lotv.spawningtool.com of all levels of play from the beginning of beta. About 25% of games are from professional tournaments. The same includes about 1500 Zerg replays, 1200 Protoss replays, and 1000 Terran replays.
The graphs are bucketed by LotV (real-time) seconds. In some cases, extreme outliers to the right have been removed from the data for a better visualization. Note that the Warp Gate timings may not be exactly right while Blizzard tweaks with the exact impact of Chronoboost, but it should still be very close.
If you want to play around with the data yourself, you can see it at
Let us know if there’s anything else you want to see from our data. We will try to see what we can do, but in the mean time, play around with the research tool to see what you can find yourself! http://lotv.spawningtool.com/research/winrates/
Also, if you could help us make the data as accurate as possible by uploading your replays, that would be amazing!
