Is that possible to implement it?
Sometimes, seeing the Groove Radar (I think it is called that) determines the difficulty of the dufficulty.
I don't now if .dwi haves this but I .sm haves that stats about the radar.
If you don't what is it, for the people does not know. Is the one with a pentagon shape and shows how much jumps, freeze, etc...
