looking great brah! You can't jump much higher than that at the wind speed and board speed you are going, you are redirecting properly solid landing, nice timing on the takeoff. I wish I had been this good at only 1 year experience. If you want to get any higher at that wind speed, here's s little trick, instead of going on a beam reach or even slightly close-hauled, 2 or 3 seconds before you jump go on a broad reach, this will build up your speed by a tiny bit, then right before you jump, go back into a beam reach, pop off the water and jump. this will get you another meter or so. You aren't doing anything wrong tho, looks great.
Agreed, you could try to bear away by about 20* before you load up and send the kite. A good way to practice this is to be on a dead beam reach, sheet all the way in and let your board track downwind for a second...you'll feel the bar start to pull harder and harder, that's when I know I'm going fast enough to really launch it. You can also get yourself another meter or two by doing it out in the surf and launching off a wavetop
