Also I still am not sure how Super Sonic charts are working. Will it be like S2/S3K where it is just the option, or will times performed with sonic be restricted to just the sonic charts, and then super sonic restricted to super sonic charts?
They won't be like freestyle, where the best time is uploaded. These charts will be for levels that have used Super Sonic in some way, so as long as Super Sonic mode is activated in the level, it could even be right at the end, your time/score will count to the Super Sonic Division only, and not the Sonic Division.
To reiterate:
For your time to count in the Super Sonic division, Super Sonic must be used within the level in question.
Final time, so i can hopefully erase any ambiguity:
You must use Super Sonic, in the level you are trying to Time/Score Attack, for it to count in the Super Sonic division.
Conversely:
If you have not activated Super Sonic in a Time Attack or Score Attack run, your time/score will go to the Sonic Division.
