Hand alternation has not been taken into account. Maximizing it is good because it allows muscles to alternate activation relax for a longer time.

Just use Dvorak. It's well proven to minimize finger travel.

I would actually disagree with hand alternation as a goal. I think optimizing first for runs (see my other comment in this thread about runs for a description) would actually allow longer periods of relaxation. If you alternate hands each key press I have the feeling that you could actually decrease the opportunity for relaxation (in the case of a fast enough typist) because as soon as one hand is done you only have the time span of a single key press before it has to activate again. However, if you can type a run of 3-4 keys with a single hand using a single rotation of the wrist, and then alternate between left hand runs and right hand runs, I think you could allow even longer periods of relaxation than single-key alternation can give.

This is incorrect. Rotating wrists or doing other rolling movements should be avoided because it can trigger RSI.

Also it's not beneficial to trade away regular shorter rest periods for a longer rest period. This is true for many activities that can cause RSI. A gentle alternation of activity and rest is recommended instead of long strikes.

Hard disagree to “Just use Dvorak”. The most common keyboard shortcuts all require two hands in Dvorak meaning that if you’re used to ctrl-c/v, you must remove your hand from the mouse for each one.

Colemak fixes this issue completely by keeping the Z,X,C,V the same as in QWERTY

You can configure shortcuts.

Nope. Not CTRL+Z/X/C/V.

Technically Colemak in better.

It is not. Many statistics are available.
