% Early - Run-Up Query

[DaveEdwards]

This week I've been reading Tom Brohamer's MPH and have a query relating to the % Early calculation.

The formula is:

% Early Expended = Second Call / Total Energy

So if we take a recent race as an example: Parx April 23rd Race 4 won by Peace Cat. I've chosen this specifically as it was a wire job to keep the maths simple.

Early Pace (EP) = 2640 ft. / 45.79 seconds = 57.65 fps.

Last Fraction (LF) = 1320 ft. / 25.15 seconds = 52.49 fps.

Total Energy (TTL) = EP + LP = 57.65 + 52.49 = 110.14.

Percent Early (%E) = EP / TTL = 57.65 / 110.14 = 52.35%.


OK, all well and good so far, but on the results chart it says that there is a 40 foot run-up. Now I presume that this means that there is 40 foot from the stalls to where the timer starts. My question is, are the times included in the Equibase results charts already adjusted for the run-up?

If not, what is the adjustment that I would need to make in order to correctly account for the run up?

Also, Ted (hopefully you read this post), do the adjusted fps calculations that appear on the POH/POR screens account for the run up or is this something that I need to account for additionally when considering a horses PPs when looking at %E?

As I'm typing it has just occurred to me that the run-up may be in excess of the official 6F distance and so no adjustment would be required at all.

Hopefully this makes sense, if not please let me know & I'll rephase. I'd be most grateful for some help with this.

Thanks.
