Test Your Backdash!
TL : DR [COLOR=#ff4d4d]@Eddy Wang[/COLOR] posted a thread the other day here about backdashes that got me thinking. This is no matter of opinion--we can measure this shit! So I figured I would measure them. Like, with a ruler.
3/3/2016 Update - New video includes all KP2 characters and is much more precise. Can also confirm that no backdash distances were changed in the patch.
Backdash As A Mechanic
All backdashes startup in 1 frame and provide invincibility within frame 1: basically your hurtbox vanishes. The only variables to my knowledge are distance, active frames (invincibility frames), and recovery (vulnerable frames). I have only measured distance, at least for right now. Later I may measure the active frames and recovery as well. A few players have done their own testing on backdash frame data and discuss it in the posts below. Backdash seems to function a bit differently if you use it as a reversal as opposed to in neutral, yielding more invincible frames if done as a reversal.The Experiment
I made a goofy yellow ruler in paint to measure simply in "units", as an objective way to measure instead of just going by eye. Each unit is exactly 10 pixels (in paint) apart.
The original video was sort of shit since the camera zoom, which occurs when a player moves away from the opponent, distorted the measurements. I've fixed that with the current video by using the Klose Kombat Perk ([COLOR=rgb(255, 77, 77)]@VengeSim[/COLOR]'s idea), meaning there is now virtually no distortion at all--any distortion which may remain is simply because the camera angle changes slightly in relation to the kharacter as the kharacter moves. This is totally negligible and I would estimate the margin of error, including distortion from camera angle and any possible human error in my measuring process to be within a maximum of ~0.4 units. Most of them are probably within 0.2 units or less.
I held block during the first tap back to ensure there is no movement prior to the dash. The distance measured is from the tip of the front toe, from starting position to ending position.
Mac mac was weird cuz his feet don't touch the ground unless you block, so I just blocked. Kotal was weird
too since he switches stance when you backdash, so I switched before measuring--just take that into account.

Total Duration, Active and Recover Frames (in progress)
I may peer review this at some point, but for now, [COLOR=#ff4d4d]@The Celebrity[/COLOR] and [COLOR=#ff4d4d]@God Confirm[/COLOR] have posted their findings below. These differences seems to be very small, which leads me to believe that distance is likely the biggest factor in determining the quality of a character's backdash. I will say that the frame data is very situational and matchup dependent. A few strings or abilities will be capable of punishing one character's backdash, but not another's.
