2. Can you count "smoothness" in the solves? R'U and RU' are smooth, RU and R'U' are not. The only thing is, half turns complicate this... Could you count the ratio of adjacent smooth quarter turns to non-smooth?
One note for that is that R U2 R' is either RU UR' or RU' U'R', both of which are not smooth in one place. I guess that doesn't work for R U2 R, but you could just assume that that's R U2' R and smooth. So if it's A X2 B, if A and B are the same way, it's smooth, otherwise, it's not smooth once.
