Awesome info - thanks for clarifying. I'm playing the retail copy without dedicated internet connection so I'm not sure if it tells you to patch. Do you know if it what version the disc is? Maybe moving from zone 63->75 will be a little easier than I had hoped.
So far I've noticed:
Speed Pads = 100pts
Barrel Rolls = 1000pts
Perfect Zones = 1000pts
Perfect Laps = 2000pts
Perfect Zones heal your ship ?10%?, but nothing else does.
Barrel Rolls take the standard 15% off meaning you can only average one attempted BR every 15 seconds (if you want to think of it like that).
But I can't put my finger on how many points you get at every moment of play. It doesn't seem to increase with speed. I could figure it out manually if I count BRs I suppose... assuming it's constant. Any ideas?
Does this still happen if you nose down the whole fall? Or if you miss the last speed boost on the high road? I mean it will always happen at high enough speeds (and you'll be forced to fall onto low road), but if it's just starting to happen at the zones you're talking about then maybe nosing down would prevent it.
