I understand.
But everyone has their own methods, I know I do.

I ain't got around to mucking about with 1st and 2nd splits yet.
I've seen some of your results, and they are not a lot more accurate than are mine.
Most of your better results are when your handicapping suggested an animal was an Underlay, yet you watch the Market, and something happens that this Underlay is now a good bet.
That to me is simply pointless and against why I handicap a Race.

But if it works for you , then that is what works for you.
