Gohma Movement comparison
6All videos held forward the entire time. Top left: stick first and early jumpslash. Bottom left: Stick first, late jumpslash. Top right: stick after rolls and early jumpslash. Bottom right: stick after rolls and late jumpslash.
Results: Stick first and early jumpslash is best. I think this is because of the following: You want to be at maximum walking speed when you roll. Pulling stick allows you to walk before your first roll and attain max speed for that roll. If you walk first without stick you do not have time at the end of your rolls to both pull the stick and get the early jumpslash. The early jumpslash is important because you begin to jumpslash on the frame of 0 speed at the end of the roll, thus erasing the acceleration frames of having to walk after a roll.
Bottom line: the above explanation is conjecture. The video shows the obvious result, regardless of why.
