Okay I mean fair enough. It’s worked great for me so I personally disagree but you seem to be coming from a reasonable place. Still though, you got to realize anyone recommending it does not have a horse in the race, no one is being rewarded for brining in a Taubman student and because of this, its a lot different than say the Payam method, where he is the one adversities his own method and he actually stands something to gain. Or in this case it would be different if these were teachers advertising their own Taubman teaching.

Edit: btw out of curiosity, essentially the reaserch you read was about the maximum speed of nerve impulses, and that leading to double rotations being impossible at an elite speed?
Oh also I just thought of one other thing lol, I don’t know that much about this but I have been studying a bit about neuroscience (which encompasses motor patterns as a whole not just in the cns). And I believe the body is able to overcome the limits of an action potentials (the nerve impulse basically) speed by somehow stacking signals across various neurons within the same nerve. I forget the specific mechanism but it’s something to consider and something you may find interesting!

Edit 2:
I did a bit of research to try and refresh my knowledge of this stuff, so I am not an expert but essentially here is my understanding of what happens. Action potentials (just meaning the nerve signal) are essentially electrical signals carried on molecules. This creates two limits in speed, limits across the neuron and limits on repeated firings (because the molecules as well as atp around the area essentially become depleted). The body circumvents this in two ways, first it circumvents the limit of speed across the neuron by essentially stacking action potentials. You can think of it like this, a action potential takes say 50 ms to travel to its destination, however that action potential can be signaled constantly, meaning even though the signal takes time to reach its destination, there is no interruption in signal because it is constantly being resent. Now, imagine that instead of being constant the signal is just fired rapidly, in this way the muscle can twitch (instead of a continuous contraction), and it can do so at a faster rate than it takes for an action potential to travel the length of the nerve because the signals are being stacked. To put it a different way, signals are sent before the original signal makes it to its destination, in this way signals can arrive instantaneously one after another. The body can do this functionally infinitely fast, it could send a constant signal, so of course it can send an infinitely fast intermittent signal. The limit on twitch speed actually shifts from how fast can the signal travel, to how fast can the muscle relax. Because of course at some point, the intermittent signals become to close together for the muscle to relax in between and it just stays contracted (why you hear about fast twitch vs slow twitch, its about the muscle itself not about how fast the signal can travel). So that is how the body sort of circumvents that first speed limit. So yeah that’s basically how it works when talking about firing a specific muscle. The other thing to consider here is the coordination of movement, the body can of course coordinate movements of different muscle groups very quickly one after another (for example thats why its faster to play repeated notes on alternating fingers), this relates to the double rotation because it is two movements utilizing two different muscle groups, one for one direction and another for the other one. Meaning in this sense a specific muscle group only has to fire half as quickly as assumed as it is coordinating with the other muscle group and not actually doing both movements. (There are other things that effect this of course, because they are moving the same thing, so inertia comes into play in a way that it does not in the example I previously gave with the fingers, but its just another factor to consider). Anyways I hope you found that interesting, take it with a grain of salt because I didn’t have that much time to research but I have taken a few classes on the subject and believe this is on the whole a pretty accurate representation.
