I almost never get SS. I just don't have the patience for it. I am sure that I could get it if I gave an S song a few more tries after I S'd it, but the frustration usually causes me to just quit playing, so I don't do it. I'm all about slow improvement. I'd rather have my overall be something like 93% on most of my songs, rather than try to get 100% on everything right off. Maybe I'll SS stuff more when I'm regularly getting over 98% without trying.
