So it really hurts me that you can't really do loadless on consoles and I would like to ask if it's possible to manually count the loading screen times and then cut off the total time of loading screens? And I think it's possible because there are programs that show the time of every frame precisly.
unfortunately, since humans can't accurately pause down to the millisecond, it's not allowed.
To add on to AwesomeGuy’s point, humans cannot accurately guess the frame that the game considers something loaded in, which makes even the use of a software not a viable option for loadless runs on consoles. This would cause discrepancies in load times (either by not unpausing the timer fast enough or by pausing it late), which would not do the leaderboards justice. Loads are removed by LiveSplit in truly loadless runs. The timers are not manually paused by a human, which is what you’re advocating for. Just yours is post-speedrun, whilst loadless runs are during the runs themselves.
