Title: sire tgi question
Post by: mholbert on June 20, 2003, 03:14:05 PM
i was looking over the tgi numbers for sires and had the following two questions.

1. the average overall is 18.3.  the sprint average is 20.0 and the route average is 19.1.  seems impossible.

2. do you think there is a significance that the average route number is faster than the average sprint number?

edited to change from trainer tgi to sire tgi

I had the same reaction you did the first time I looked at the sire TGIs. But then I thought about it a little more and realized that the overall TGI is an average of the best a foal has run, regardless of distance.  

Consider this example for 1 sire with 4 runners. The tops are:

Foal 1-- s-20, r-19-1/4
Foal 2-- s-22, r-20-1/4
Foal 3-- s-18, r-20-1/4
Foal 4-- s-20, r-17-1/4.

The sprint TGI = 20. The route TGI = 19-1/4. The overall TGI = 18-3/4 (rounded).


Most runners debut in a sprint and lot of these horses run once or twice and then retire or aren\'t heard from for a variety of reasons, i.e.,injury, breeding purposes, relocation outside the US. The point is they never get to run routes. The horses that do usually have some experience and are older and more physically developed. So I think it makes sense that the route TGI is lower than the sprint TGI.

thanks for the clarification.  i was thinking average in the, well, average sense.  once you explained it as average of best, makes sense.
