I'm seeing a lot of overlap with the "No Undos" and Any% categories. I tried messing with the Undo button and couldn't find much use for it as a semi-casual solitaire speedrunner, since it's not like some hint or skip button which can always save time. Is the Undo button a viable strategy for more competitive runs? If not then I think it'd probably be best to merge them.
I could be wrong about this, but I think solitaire rankings started a tradition of considering the undo feature as cheating. It's not explicitly stated but I think runs that use undo might even still get rejected from the windows solitaire categories. I don't know if it could possibly optimize the game over not using it, but it can be used to save a potentially very good game.
I don't really have an opinion either way, going for a good game and realizing you need to use undo pretty much means the run is dead for me so I'll probably never submit a run that uses it.
