What it does

Several decisions stay in flight at once so each answer can arrive near its scheduled note. A recorded performance can be replayed without live calls.

Maker-reported (not independently measured by JevMade): About 400 ms per answer, so each 100 ms slice is asked about 500 ms ahead (author-reported) · Round-trip p50 of 356 ms (source comment)
