Beyer Speed Figure question (Belmont)

[joeydb]

Steve,

If you get the chance to ask Andy on a future occasion, I was wondering if the comparison of American Pharoah's Belmont performance versus that of Secretariat would change either quantity from a speed figure perspective.

Andy has said on previous occasions that Secretariat's Belmont would be equivalent to a 138 or 139 Beyer Speed Figure.

We also know now that American Pharoah's figure from Saturday was a 105.

Does this 33 or 34 speed figure point difference make sense with the 2.6 second difference in observed final time? Also, both horses led at all the points of call so the observed time throughout the race is their time, with no lengths necessary to apply as a delta.
