Thanks for bringing this up, I'm not sure on the rubber banding myself so I've linked it to the TASers if they're interested in doing any work for their own interest. For CTR speedrunning it won't have any application I'm afraid. 2p already makes some tracks easier, like Blizzard Bluff where assets are removed to increase performance, but no 2P mode is allowed/possible for TTs or speedrunning.

But hey, fun to look into right?
