I dont know if thats another one of your old sites or not cybrax so I cant really tell, although the information given is exactly like the video you recorded
I have a question though. After the first checkpoint, when you hit that blue ramp, instead of going up that vertical wall and taking the normal route, wouldn't it be faster to simply jump on top of the wall to your left (this is right after that blue ramp after the first checkpoint) and spindash and jump and land on the next blue zipper ramp that is right after the three loops next to each other?
It's hard to pull off, but if you manage to do it, it seems to save alot of time. But hey, what do I know about SADX? So, maybe going up the vertical wall like you did in your video is faster...
