I noticed that the current run stops timing as soon as the final boss dies. I'd argue that timing should stop at last meaningful input-you can still move and extend the game on last spells, so timing would stop on failing the final last spell. This would make the 25:27 run a fair amount slower than it currently is.

This is also how Elainespencer (who has a 22:xx FinalA and low 23 FinalB) and I timed runs about a year ago.
