Mike is dead on here.
You jump at 100% and enter the competition later if is your wish.
One thought about bar rotation / clearing of…
is (assuming a left foot takeoff)
What is your right arm doing from ground release to your top of the bar position?
If as I would currently guess, it is continually lengthening above the head and away from the torso, then the "action/reaction"
most times, is to "touch out" bringing the hand/arm forward towards the knee causing an extreme sit out on top of the bar.
Using an arm block will transfer some swing energy to the body whole and better still, will facilitate lay out of the arms at the side.
This will speed bar rotation and then the tuck of the chin will be more appropriate and effective.
