I called it Snowy Park because I couldn't remember the name and you knew which level I meant anyway >_>
having done all the SS' now, Rings should definitely be the thing you do for the dedicated Special category; Times/Score I guess are up for debate. Seeing as you can boost, but still need to collect enough rings, which in later stages is fairly hard (FAK U SS7), it might be worth putting in Times. Scores, from what I can gather, like the levels seem to be mostly time bonus, with rings being worth 100 each; having said that, I got a time bonus of 0 for my SS7 completion, so I'm thinking that it's worth tracking T/R/S for the special stages after all.
Also, unlike Ep1, there are enough rings in every boss level to turn super, and being invincible could be pretty damn handy, so each boss should also have Sonic/Super Sonic divisions?
Also as cryptic said, the platforming parts of SF1 are part of the autoscroller, the only thing that isn't is the boss fight at the end.
