But make it 1-8 note grade1-grade8 for simplicity IMHO. The
grade1-grade5 for tracktype is an error in itself...
It does not matter if it's easier or more difficult - the main thing is
that people using it should know what they enter. With the current
values like good some mappers just use it without knowing what is behind
the value - therefore often rendering smoothness unusable - because the
values are unrealiable.
