I was wondering when the perfect moment is to pop off the water with sent jumps?

approach with speed, steer back the kite aggressively from 10 to 12 or even 1, hold the edge, then pop off the water. but when? where in the window is the kite? as in how far up over your head? if you pop off too early I guess you'd end up not going very high but rather a long way downwind? If too late the kite will overfly and result in a pendulum ass bomb?

I've been getting jumps over 5m, my pb is 8m (according to trace) but I'm rather inconsistent. half a season of jumping under my belt, I'm keen to get over 10m and the seabreeze is back :-)
