Friggin horrible! BUT that just means there's so much room for improvement... if that was perfect jump form then you would have trouble gaining more inches 

1. You're going to have to run faster.
2. You're going to have to learn to come into the basket at an angle.
3. You need to jump further from the basket at take-off (I have this problem too).
4. You're barely even.... planting. I swear, on both jumps, I thought you were going to take off from one foot.
5. Practice jumping without the ball first to work on technique and learn to use your arms when you jump (the swing).

btw as for bananas, start off with like 6, no need for 12 right now..

you need to do some submax work, just trying to "act" the part of some high level jumper.. by that i mean, come in on an angle & plant deeper... you can do this submaximally, maximally it won't happen until you get in some submax work.. so just go light and work on getting some knee bend, you barely bend at all it's pretty crazy haha.. it'll probably have you jumping lower initially, but once you start improving your runup and plant depth, you'll start getting up higher.

don't worry about run up speed as much yet until you work on getting lower in that plant, it definitely won't happen until you can plant deeper at your current speed.. think about throwing yourself into the ground before you jump.

work on 1,2&3 step runups.. 1 step into a half squat style plant and jump.. etc.. eventually when those get better, should happen fairly quickly, work on 2 step, then 3 step etc.. warmup with those as small technique drills before your jump sessions, to help reinforce some of those things you need to do.. when you go 'fast' and do a big runup, its hard to change things.. with 1,2,3 step drills, you can really focus on those changes much more effectively.

peace man, look forward to seeing some big progress over next 4 weeks, much to be made

What if he uses a one-leg jump?

You don't measure 1 leg vertical from a standstill, the technique requires a run-up. I would advise to stick with two-legged VJ for now.

A progression you can use to learn the drop-step VJ:

1. stand on non-planting leg, arms out in front of you at shoulder height
2. make a BIG step with the other leg, planting far in front of you and therefore lowering your center of mass (COM); swing arms back forcefully at the same time
3. make the last step, putting your non-planting leg slightly in front of the other one; JUMP while at the same time throwing your arms in the air

Do this to practice those most important last two steps. This program has to become automatized and you can easily manipulate how far you lower the COM to get into the mechanically most advantageous jumping position. To learn jumping from a full run-up just add steps gradually, beginning with one, then two, etc.

i love this; i feel it in my abs

My explanation was probably horribly unclear, but what you did there was not what I meant at all . You probably had a good leg work-out from doing that for 20 minutes a day though, haha.

The goal of that progression is to learn to jump. The idea is to learn the drop step vertical jump in pretty much one session (it usually does not take more than a few trials to get that right) and maybe to refine it in the following weeks. This is however not a strength work-out or something. In order to learn this movement program efficiently you have to do all the steps together in a fluent motion and jump at the end. The goal is to make this as automatic as possible, practice the whole movement until you don’t have to think too much about it. If you are there, perform the movement quicker and more explosively. It should not take long to accomplish that, most people can do the movement with okay speed within a couple of efforts, although it might take a while to jump maximally with it.
