After discussion with the other mods. We have come to the conclusion of not adding a scores board. Simply because this is a page for speedrunning the game and not for scores.
Personally, I don't see any reason right now to add them, mainly because it would only really be one group doing them. If there were to be more of a demand than we could go about adding them. Until then I don't see any reason to do so.
The only thing you can do once you handshake is end the final cutscene. Which honestly isn't something we should have to watch, mainly because it doesn't add anything to the run. Once you handshake you don't have any more actions to complete. And once you hit credits you can do the same skip ending that you can do while during the cutscene. It just doesn't make sense to have to watch a ~7-minute ending, which doesn't add much to the run.
Personally, I find waiting for the cutscene to be moot. If someone chooses to do Leo's end instead of Vincent's if their own fault. If you want it to be fairer then you could split the two and have one for each end.
