But if this is true, then I suppose that if consecutive keys are pressed by fingers on different hands, the coordination is more difficult, because both brain hemispheres need to coordinate on the timing. So it is not obvious to me that alternating hands is preferable
On the flip side: there is more potential of interference between pressing keys with different fingers on the same hand than pressing different keys with different hands. (Either mechanical—moving one finger does affect the other fingers on the same hand—or neurological.)
I don’t know the relative importance of these factors.
