What is your target technique? Instead of 120 degrees, what do you want to do? What is it that you're trying to do with your bottom arm?
And what do you mean by the drive phase (it sometimes means different things to different people)?

If you think that you might not be jumping on takeoff well enough, then that's probably true. That's two main flaws so far.
Of your four limbs, your bottom arm is (arguably) the least
important what you need to cognizantly do with it to jump high. I suggest that you focus more on your top arm and trail leg first. If my guess is correct, that's now four flaws and counting.
But as Vcpvcoach said, you'll have to post some vid so that we're not just guessing.
