Adjusted times (according to Bernie Hettel, racing operations manager):
1/4: 24.03 (difference of 1.75)
1/2: 47.62 (1.65)
3/4: 1:11.52 (1.67)
Mile: 1:36.32 (2.49)
Fin: 1:50.07 (1.78)

If the pony did trip the teletimer, which is believable, why would the differences in the times vary from 1/4 pole to 1/4 pole? They should all then be off by the same amount.
