Heroes of the Storm
When each battleground's objective becomes contestable, and how long until the next one — read out of 115 replay files rather than repeated from a guide.
An objective appears, holds for a measured 30.06 seconds, then unlocks. Across 156 Cursed Hollow tributes not one was taken sooner than 36.75s — a 30.06s lock plus a ~6.7s channel. Every figure on this site is timed to the unlock, which is when you can actually contest it.
The community reference adds that lock a second time on two maps. Cursed Hollow is 50–90s, not 80–120s, and Alterac Pass is 110–150s, not 140–180s. Volskaya's capture point charges in 48s, not 52s.
The Heroes wiki and Nexus Compendium both updated from the 2021 community sheet within days of it being posted, so their agreement with it proves nothing. Replay files are independent evidence, and they reflect the build actually installed.
