It's a funny thing about those ratings, they seem to be systems rather than ratings.
They pick enough longshots to make it breakeven at TAB prices, yet bear absolutely no correlation to the variance of traditional ratings.
In other words BR ranks have wide variances.
Backing overlays and underlays has no degree of worth.
Top rated that are favourite are worse than favourites alone.

Not potting them, but I think the term "ratings" is a misnomer in this case.
