I've recently gotten into this game and decided to start things off with some IL's. Then I noticed you can't submit times with milliseconds for this game.

It seems weird to go after the rules that states "Goes by in-game time." when you cannot actually submit the real in-game time as no milliseconds are allowed.

Someone could hypothetical have a "39.99s" and another "39.01s" and they would both be tied as "39s" which doesn't seem fair.

It seems rather weird when Shadow of the Colossus (2018) allows milliseconds and simply states the full-game rules as "When submitting runs, please do not include milliseconds in your time. That slot exists solely for individual time attack submissions." and IL's as "Include milliseconds in submissions.".

It seems to already have a solution at hand so why not this game? Any particular reason for this decision?
