Thanks wesmip1, I'm using a horses winning % as the basis of a system.

It will go something like this:

1) A predetermined % Win SR must have been currently achieved or will be achieved if the horse won this race.
2) I'm looking for a minimum number of wins, it'll be more than three I'm guessing, might even be up to seven.
3) I'll rule out 2 y/o's & 2-1/2 y/o's
4) I'll rule out horses older than 5-1/2
5) I'm looking for this SR to hold up over recent campaigns.
6) It does not have to have won this time up.
7) I'm NOT looking for a Black Caviar, I'm looking for a horse winning it's share of races, some in the Metro, preferably an interstater or from NZ.
8) A minimum price of probably $5
9) Study of volumes of form guides show starts around 6 or 7 plus up to nearly 20 is the range where the bets are to be had.

I've "followed" this selection method for many a year and will start to punt it.

cheers and thanks Wesmip1.
