Duane,
I will ask Bob if he can do something about the USATF site.
As for the topic of discussion, I feel this does address the concerns for an expired course that hasn't changed or has a minor adjustment where a 10 year extension would be granted.
Here is what I was referring to:
To obtain a certification with new 10-year life
If it is desired to extend the course’s expiration date then, after applying the adjustment procedure indicated above (including addition/subtraction of distance with intention of keeping the course length unchanged), the entire course must be remeasured at least once. Thus, all portions of the course not involved in the current modification must be given at least one new measurement. This will result in a remeasured length for the full course, calculated the same way as for any normal certification measurement (including the SCPF in riding constants). If portions of the course have been remeasured only once, the remeasured length must be within 0.08% of the intended race distance, and if it comes out shorter than the intended length, distance must be added to the course to bring it to the intended length. If agreement isn’t obtained within 0.08%, or if the measurer thinks the course should be shortened, then a second measurement is required, as for a new certification.
