Although the Multi Segment category is not accepted, we can still talk about it between players.

Just copying an auto save to a manual backup to reload more easily, lost wastes seconds:

Here, the observation apparently like the example of this video (from 3 to 4 minutes) on each manipulation we would lose seconds which are not always mentioned if we do not approach the minutes too much above. So why, since we're not playing, good question.

Enough to discourage the Speedrun Multi Segment, I can't see myself relaunching the game on each try to copy my Save Auto from a USB key. Worst ever Save system.
