What an extraordinary claim.
> Yes, and for good reason. It means the student can skip learning 11/12ths of the required muscle memory. That's a very significant, and very measurable gain.
That seems to make sense. Unfortunately you can't provide any proof or evidence. I could claim that my one-key keyboard with 88 transposition buttons was superior, but I don't, because it's not.
I just did. Mathematical proof.
How much evidence must I provide your condescending sensibilities? Do I have to hunt you down, sit you in front of a Janko keyboard, and force you to learn?
Is that right. I don't recall seeing any theorems, lemmas, axioms, or really anything resembling proving anything, mathematical or not, but I have seen a lot of blustery naïve rhetoric. Just saying an accordion-nightmare keyboard is better, does not make it so. Please pardon me if I remain skeptical.
> How much evidence must I provide
How about a study that addresses your claim: "It means the student can skip learning 11/12ths of the required muscle memory. That's a very significant, and very measurable gain."
You are making a big claim here. Not sure why you're surprised that someone is asking for clarification.
