Smash Lord
An average isn't that useful. Ryu's frame data should include the range of values each move's startup can be. Different people and different controllers will hit different numbers; if you have fast fingers and a good controller, you'll be able to hit the frame 2 jab easily. If your A button is a tad sticky or you can't release the button quickly, you'll hit the frame 3 or even frame 4 jab. I'd wager the top Ryus will make a point of learning the timing for the frame 2 jab.I mean I'm aware of press and hold but....does how long you tap actually affect the tap normal? This character's precision levels are literally off the wall.
So Ryu has varying frame data...within his frame data, if this is all correct. Good lord that's complicated. I guess your best bet is to average it out (reasonable input, etc.) and use that number. On average Jab is frame 3 IIRC, so that would be what I'd go with.
His frame data should look like Jab (light) startup: Variable, F2-4
It'll have to be made clear that it's variable startup and not just hitbox active frames.
