I think the timing method could change since it's based on the first input frame, HOWEVER, it's not everybody who does have an inout displayer for that and so it makes retiming really hard and inconsistent, I'd like to suggest if it could starts on the first frame the screen gets black after selecting a file so it would be more consistent like this.

Couldn't we just count how many frames between pressing the first input and screen turning black? But yeah, i know that retiming is kinda garbage rn, but i believe the best approach would be someone adding a feature in game that we could use as reference

We could try both things, althought even knowing how much time it takes to turn the screen fully black, we'll still framecount it from the first input given since final time somewes/YFT will give to you is based when you set the first frame, sadly it isn't like a LiveSplit or something around that.

Used Somewes.com to see the time it takes to the screen to turn black after the first input and it showed me 0.733, so if someone wants to start the time when it turns black, just put 0.73 on the LiveSplit or if the timing method changes, put -0.73 on LiveSplit, that's it I think.
