Yup, we don't add anything to the center distance and it "just works".

With regards to the specs - the center distance equations are the same. You'll notice the WCP calculator has a field called "center distance adder" that is set to .001 by default - that is where the term comes from. Leaving this at one thou is fine if you want. Doesn't seem to make much difference either way. If you needed to be within one thou of a specific exact distance for belts to work, you wouldn't be able to run them with exact centers anyway because almost nobody holds those tolerances in FRC.

As for the rest of the specs - keep in mind they are referring to mechanisms with far higher runtimes than FRC things. They are very conservative.
