Using the old MPH and entering TM variants

[Jeebs]

I had emailed Ken Massa the other day about manually entering track variants into the old MPH software, and he stated that when he and Tom Brohamer were doing their own variants, 1 point = .15 fps, so if a track was 3 points fast, they would enter -0.45, or if the track was 3 points slow, they would enter +0.45 for the adjustment.

I see that Trackmaster has a variant on their PPs, but am not sure how to interpret it. For example, if a variant for the race is 20 (20 points slow), does it mean that its 20 fifths (lengths) slow, 20 tenths slow (which would be 10 fifths slow), or is there no way to make heads or tails because their formulas are proprietary?

hello jeebs

Glad to see you got MPH working

What I came up with, might not mean much to others but this might be a starting point, when working with the TM DTV

After many trials of trying to figure out how the TM DTV could match the DRF DTV
I found a system that seems to be working fairly well.

What I did was establish a variant par of 18 for sprints and 20 for routes

When I use my Phase 1 program the numbers are adjusted based on the DRF
variant. So I needed to equalize the TM DTV to the DRF DTV since I use TM PP's.
What I did was find pace lines were the horse ran at the exact same distance and same track and ran wire to wire with no beaten lengths
I kept redoing the lines with different variants until the EPR and TPR
numbers were exactly out of the Pace Makes The Race Book And what RDSS shows on the TPR screen

Those numbers were 18 for sprints and 20 for routes

Now if the TM is 10 I take 1/2 of the 10 ( I round up odd number variants )
and add 5 to 20 and enter the variant as 25 in a route or 23 in a sprint

for example using this horse
#1 Dilatory
Line 1 The TM DTV is 6 and its a route
so I take 1/2 of 6 = 3 and add it to 20 and get a DTV of 23

I'm lost. Would I multiply that 23 variant by +0.15 (apx. the FPS value of a length per Ken Massa) to get a variant total of +3.45? Or, do I take the initial TM DTV of 6, multiply that by +0.15 to get a variant of +0.90?

Hi jeebs

No I was just showing how I equalize the DRF variant which comes from the
3 year best speed rating
The Trackmaster variant is the difference of a man made par time
If you want to use a old program that used the DRF variant
you have to make some kind of adjustment first

A TM DTV of 20 is not the same thing as a DRF 20

Lets me know how things work

I think the TM variant is different for each distance, closer to a Beyer scale variant.

What version of MPH do you have?

I will see if I can decipher how to convert it.
If you download a TM chart, it might be easy - they used to have the raw time, the variant, and the adjusted final time all on the same line. I have not used their charts for a few years, so not sure it is still like that.

Hi Tom

The DTV in RDSS which I need to adjust to the DRF DTV uses a total DTV for the day, Sprints or routes


Here are a few examples
March 11 had a good mix of route and sprint distance at Parx

The DTV is 10
I went back and found some sprinters and some route horses
who have run again and we can see their pacelines all say DTV 10
the same for routes, sprints and horses changing distances

I have Version 1.3 from 1995. I have the option of entering in Beyer figures or an FPS variant.
