Blake how many pictures per second your camera takes.
i can do 1000, but anything over 250 fps needs too much light.
it doesn't matter though. still frames and slow motion provide body placement.
you can have perfect body placement and crappy timing and only throw 275'.
the timing factor/acceleration can only be seen full speed (or very close to full speed).
For really high frame rates one needs additional lighting then. That makes sense from a technical standpoint.
It is completely another thing to be able to measure somebody else driving and seeing when they begin to accelerate and how fast each body part moves in the beginning and how fast they accelerate to which speed in which amount of time than to be able to perform similarly yourself. There's no question about that.
Many people probably can't accelerate as fast hence start accelerating as late as a top pro if they want to delay beginning of acceleration as much as possible. I'm not saying that the pros even do this. That's just the recipe for theoretical maximum rate of acceleration near the rip and thus maximum acceleration as well in the proper place.
The possible benefit of measuring how a top pro or yourself are performing is that you know what's happening, when and how fast. This allows you to conceptualize the order of events and how much effort you should do with each muscle group and when to do the work and how(powerful vs quick). This gives you a framework against which to try to compare what you are actually doing. Then you can check if you think some other way or performing things might be better on a theoretical level and concentrate on changing to the new version.
Once you have footage of yourself performing in a different way you'll know with higher confdence that you've done everything the way you meant. Then you'll hopefully have a slightly higher probablility of making a correct appraisal of which version works better for you. Repetitions are always necessary in order to make higher confidence evaluations. If changing only one thing in your form results in for example 3 mph more throw speed with 1 mph/s/s of more acceleration at the rip and 15' more D consistently go for the new version. Or take the change even farther and see if you can get more D and see when you loose too much accuracy and consistency to determine when you're gonna take things to extremes and when you need to maximize accuracy and consistency. The numbers were arbitrary but you can get rough estimates of velocity and acceleration by measuring the changes in position between frames.
If a wrist moves an inch in 0,01 seconds (two consecutive pictures with a camera that takes 100 pictures per second) you have the speed of 100 inches per second -about 6 mph. Let's pretend that 7 pictures(0,07 seconds) later the player accelerates so much that two consecutive pictures show a difference of 3 inches -about 18 mph. Then you know roughly where the player started accelerating and now the speed is much higher. How do you determine what an inch is? Without computer aided programs there are several factors that mess up the estimations. If you know how tall a person is in inches and have a picture of them standing up or showing a measuring tape that you can see an inch of you have that. Measure that on your monitor screen and use that and you can estimate everything.
Knowing these tidbits allow you to plan a training regime and if you're inclined you can plan and prioritize a research plan. IMO it is more important to identify what you are doing wrong or differently from theoretical best practises or good players. Then just change. Just is easy to say but when you get down to changing things you'll have to know what you're trying to change and concentrate on it.
If you don't know exactly what you're trying to change into which direction and how much and what it takes from your body to achieve that it's a matter of luck and trying to do things with as many ways it takes for you to identify what you did in the moment of performing and guiding your body. Nigh impossible if you're not really concentrating and making several attempts at each version.
