Sartin Energy! program

[njcurveball]

I need some help and perhaps this is a dead end, but I figured I would ask the smart people on this board.

I have some formulas to estimate the Early, Presser, and Sustained values from the old Energy! program.

One formula, Sustained, is very close. Those numbers usually are in the high 60s to the low 70s. (No, this is not a weather report).

Early is usually in the low 60s and Presser is in the mid 60s.

What I am asking is that if anyone knows what Sartin used to "fine tune" these numbers could you send me a private email. Even a hint might help. It has been a while since I looked at this stuff, probably everyone is in the same boat.

For those who have not seen the program, it basically breaks the race up into fractions and assign percentages to each fraction. Sartin combined the first two fractions in their Median number.

SO for example, I have a Sustained rating of 71.24. The second call is 31.9% and the fps is 56.17. The 3rd fraction is 32.58 and the fps is 60.

How do they combine these to get a number in the 70s?

thanks for any help!

p.s. I am not designing some program to sell, just tweaking my database.

I think it's called voodoo! :D

For a numbers cruncher like myself, voodoo is a hard concept to attempt to duplicate. :eek:

Everything else in the program flows logically. Do you think they would just put in some wacky multipliers for these ratings?

Back "in the day" they were golden and much better than compounded velocity.

The only 70s I know of, is the M%

F1%+F2% / F1%+F2%+F3%

I make those numbers from the HTR fps exports using F1,2, and 3.

Good thoughts Tom.

I have mixed all of those percentages, but these numbers are backwards. Early in the low 60s, Sustained in the low 70s.

But you have given me another idea to try.

Thanks!
