I don't really agree about the similarities. I mean, studying closely things about plants etc, I've discovered that the best jumpers are those that drop quite a bit on the penultimate step in a two footed plant as well. You're currently not doing that very good in my eyes. To me, that's the part you could improve sooooo much. Lean more on a side and "be like water" to quote Bruce Lee.
I've also seen on Vince two days ago in his plant how well he puts that right leg and rotates on it, and keeps on rotating until he puts the left leg on the floor too. He's kind of unique in that regard since the people I usually see - they rotate as well but they are "stiff". He just lets his limbs be elastic and "bend". It's really hard to explain what I mean, but it's easily visible. And no, I'm not that crazy, mind you.
So to me, if you'd look a bit into the penultimate and tweak on that, you'd get higher.
