I ran 12 months of Betfair results. Laying the fav only, moving rocks around the paddock. Laying the top two a negative. Laying the top three a negative.
Laying all =<$20 a bigger negative. Laying the field a positive, but be prepared for one losing week in four and four losing months. This was every race. I know that there are races in there that would not pay ever and a culling exercise could straighten some of the bumps.
