Key timings
These timings come from 98 recorded build orders by 4 players. Buildings are timed when construction starts, upgrades and morphs when they finish, exactly as the replay records them. The median player finishes Metabolic Boost at 3:02, with the middle half between 2:59 and 3:05. Timing data is still thin (n = 98 replays), so expect these medians to move.
