The jump was relatively easy but I got affraid to get higher because I could only go up in increments of about 2 inches.
So where do I stand compared to the guys who do it a lot? I have absolutely no comparaison point.
Well, it really is necessary to know the height in order to be precise. When you start doing max height for box jumps, once you get to a high level, a mere inch can make the biggest difference, just like adding as little as 2.5lbs to a 1 RM once you're close to saturation. I guess knowing your height might be a good start.
I'm certainly not a pro box jumper, nor do I do them a lot (especially not for max height). The highest I jumped was 50.6 inches. Obviously this is done with both feet stuck together and from a standing still point. Both feet have to cleanly land on the box (or at that point, plates or steps). Not that this is the ''official'' way to go about it, it's just the way we did them.
The most I've seen in Crossfit from a standing still point (no one or two steps to help yourself), is around 56inches. If you can get up to 60, then I believe that is true athlete capabilities.
But if you're doing this in trying to improve power, you're better off doing vertical jumps. Max height jumps will greatly depend on flexibility as it focuses more on how high you can bring up your knees ( sometimes as high as your ears). If power is the objective, it should be done by working on making your centre of mass travel.
If you're able to get it with ease, without taking any steps, to a midway point between your nipple and top of shoulder, then you probably can get it to shoulder height. If you can do those jumps, then man, start working on some standing flips!
