after some discussion, the mod team (myself, @pinewarbler, and @WolfWitch) has decided to clarify the timing rules a bit and streamline the "timing end" especially. most categories now use the following timing rules:
Timing Start
Time starts as soon as the main store screen loads (when the shopkeeper Goose appears)
Timing End
Time ends on the first black frame of the End of Day screen.
existing runs will be retimed to match the new times, which means they should all be shorter by a few seconds. yay!
