Idk how strict you are with beeing mercifully and verfifying or resctricting...but imo this run ( https://www.speedrun.com/Geometry_Dash/run/yl9jgg3y ) isn't 100% by not collecting the coin at 15:47...I don't wanna put the runner in a bad light, I'm just curious...sry if this is inappropriate :/

EDIT: just noticed, he restarted the level AFTER finishing up...because he didn't do it at once, I didn't expect that still to happen, so a big sorry for the potential blame at this point right away by my side at the runner! But another question consequently: Of course, re-entering that stage is allowed, but don't have all 3 coins per each level to be collected in one run with finishing? I mean, the same way as it doesn't last to collect them and exit world I would've thought, doing e.g. the "easy" 2 ones first so you got them for sure, and then trying over and over again for the third till you got it, would be unintentional. Because - for me at least - the real chalenge never was to collect one of them in a single full-run, but to collect all of them 3... Interested in your answers! :)

Technically, the game works in a way where you are allowed to do multiple runs of individual coins and still get all 3 coins without getting them all in the same run. So from the game perspective, it's completely allowed. But from the perspective of a 100% speedrun, it is debatable due to the '100%' aspect of it.

In my opinion, I don't think it should be too harshly moderated as doing this will cost the runner over a minute, so doing this strategy would be sacrificing time for less risk, which is quite common in speedrunning. That's just my opinion, though.
