For example: Sagat and Bison are in the same wake up timing group so a specific jump in timing on them as they are waking up always works. But It doesn’t work on Dhalsim cause he wakes up slower.
Is there a list of the different wake up speeds for each character? In CvS2 there was a list composed where half of the cast woke up at the same time, so you could do free jump ins on those characters, but not on others.
I know there is such a thing in SF4, but no idea if anyone took the time to figure it out. (Please do!) This knowledge would be useful to figure out who you could jump in free on and which setup you would need to do once you learn their get up speed.
