Brumby,

As far as the "value threshold" goes, in almost all cases I only focus on my top rated, second-top rated, or equal second-top rated horses for potential overlays. I can sometimes bet the three horses in a race but this only happens when I've confidently rated the public favourite quite unfavourably. These are usually good betting races for me. If I go much deeper than my top 3, at any time, the strike rate and profitability is prone to going out the window.
