Less standardized run-ups at Aqueduct than seen previously?

I'm not sure if this is something equibase is just starting, or is specific to Aqueduct, but Saturday's card shows races at the same distance with slightly different run-up distances. Some tracks are always reported to have the same run-up distance for the same length race. Others will run the same distance with different run-ups, even on the same card. But these tracks only have so many different run-up distances that they use, not an endless number. And the distances normally differ enough that one wants to know of them. At Aqueduct on Saturday, we had 6.5 furlong races with run-ups of 18 and 24 feet, and 8f races with run-ups of 36, 32, and 35 feet. I've never seen anything like that in the run-up realm. Standardization may not be completely gone, though, because the 7f Bay Shore and Carter are both reported to have been run with 40-foot run-ups.
