Also the Del Mar mile has a 180 ft run up and Gulfstream 7.5f turf races have a run up of 260+ft. The biggest difference with Los Al is the track configuration. It favors horses on the lead because there are few true straight stretches. Kind of like a Bull Ring.

I stand corrected. Mark's explanation regarding the track's configuration is best; but I stand by the fact that the final time is dependent on the exertion of the early pace.
In fact, I will postulate that Uncle Lino ran the same "energy exertion" race in the Los Alamitos race as his race in the Santa Anita Derby up to the mile marker.
Uncle Lino's paceline from the Santa Anita Derby up till the mile marker:
22.0 2F 45.1 4F 110 6F and 136.1 mile time
2.5L behind at 2F; 3L behind at 4F; 1.5L behind at 6F; and 4.5lengths behind at the mile marker or
Uncle Lino ran 45.4 for 4furlongs and 110.1 for 6 furlongs and 137+ for the mile.
At Los Alamitos:
Uncle Lino ran 6 ticks slower at the first fraction or 47.0 for 4furlongs therefore according to Huey Mahl and Jim Bradshaw; one unit of energy at the first call equals two units of energy at the finish, we expect Uncle Lino to run 12 ticks faster at the mile marker.
If we subtract 12 ticks from the final time of 137.0; we arrive at 134.3(fifths)
Actual fractions for Uncle Lino in the Los Alamitos race:
47.0 for 4F 111.0 for 6F and a mile time of 134.3(fifths).
Great answers, Mark...
