This is going to be QUITE a wall of text, isn't it?
We're going to find the maximum percentage that can be saved on official levels! Some of these records probably already exist, but the problem is, sometimes you have to hunt them down. So here they are. I will do my best to keep this list up to date.
If all levels in a category have been tested, to shorten the list, "All levels in this category solved" will be added, and the ones resulting in 100% will be removed from the list.
Oh, yes, and for fun in DOS, I'm covering them all, and updating the post as I go.
