Barny Read up on William Benter.

Identified around 140 variables that could affect a race result. 24% POT at around a net value of $50 Million.

when wesmip talked about filters he would often identify 2 sets of ratings, the use of a wide barrier and Days last start. The ratings were very unique but in the background many other variables gave him this total.

If someone were to say use the top rater from Don Scott racing and sports and the unitab top rater and sky ratings you probably are doubling your points or allocation on one particular variable.
