These times come from the run's own timeline. Thinking time is real time minus playback time. In-game time is the game's own clock. Playback time runs a little longer than in-game time because of loading and animations.

The recording continues after the goal was reached; anything played after that is not part of the run's time. Whole recording: in-game 00:00:30.7 · real time 00:01:13 · thinking 00:00:42 · 17 playbacks · 17 tool calls

Verification

This is the tooling's own check (a fixed copy of aas check), run when the Archive received the bundle. To check the hashes yourself, download the bundle and open it in the verifier. It recalculates every sha256 and adds up the playbacks against the totals, in your browser.
