If PC was consistent as a platform I would agree with Obiyo but considering how much hardware can play into load times between harddrives, processors, gpus etc, idk if relying on RTA only will ever be a true measure of who has the record. As much as it sucks I think if there is going to be a truly competitive leaderboard there will have to be a retiming done. Mods can decide which runs to check the retime more stringently (top 3,5,10 etc) but I can't see a way to have a realistically accurate leaderboard without some kind of retiming.
