Sorry, but I won't concur that #2 is accurate. The SCPF is there to compensate for wobble, or when the SPR is not actually ridden. Therefore, while a 10k is measured to 10,010 meters on the Jones counter, the actual course length will be somewhat less than that.

While I can record the same number of clicks on both rides of a 5k, and occasionally of a 10k measurement, I would bet that if a tape was used, my total course length would be shorter than 10,010 meters.

Nit-picky, maybe, but we should not tell runners that a 10k course is always 10,010 meters, or that a marathon course is always 42 meters long. That is not necessarily correct.
