I practiced different jumps on flat ground. hitting [space] & [w] at the same time, hitting [space] then [w], hitting [w] then [space], and I jumped around like an idiot while running from place to place in my day to day activities (even though they say this slows you down). It seemed to help me get a feel for the physics of the game and therefor makes your fingers take action all of their own as needed.
All that being said, I still hate datacron hunting
(have all but a few on my first 50, only one or two on my second 50, and none on my 43
I keep saying I'll get them one day.)
