Hence bursty sprint speed is more important than sustained speed. Mechanical keyboards are quite good at bursty sprint speeds in my experience. Sustained speed is another matter, I can see where the power return of each key press would cause soreness (like wearing shoes with springs), but its not a problem I have as a programmer who mostly just sprints.

Yes, but you don't have that problem on a mechanical.

Right, the question is not about whether speed matters, but what kind of speed matters. Do you type for a minute without pausing?
