Generally, additions like that (or to the C-C distances on gearboxes) are made to account for manufacturing tolerances. By fudging it a tiny bit large, you give yourself room for error while still getting a tight belt. (If it was too tight, you could always fudge the hole back a little and survive. It's far harder to make that happen when it's too loose.) That particular number would come from the calculator maker's past experiences, and may vary for other applications.

Most FRC teams can't even manufacture to the tolerance of 0.001" anyways...
I'd say the number of teams that can make that happen grows annually (and maybe beyond the FRC growth rate) as precision manufacturing gets cheaper and more widespread. Whether that ability is in-house and/or whether they take full advantage of it is another topic.
