Why we timebox perf captures on Quest builds

Weekly captures beat heroic crunch. When learners ship VR scenes, the biggest failure mode is skipping profiler saves until the night before demo day — then nobody can tell which change blew the budget. We ask for a fixed window: twelve minutes, same scene, same movement script. You save three snapshots and annotate them in a shared sheet. That sheet becomes the cohort's memory, not someone's laptop Downloads folder. The ritual is boring on purpose. Boring processes survive time zones. If your capture drifts longer, you are probably chasing noise — trim the scope and log what you deferred. Finally, we grade the write-up, not the milliseconds. Honest notes about uncertainty beat polished numbers that cannot be reproduced.
