I haven't looked at a back/lay ratio but I have a price filter of $7.40. I haven't analysed the prices yet but may do so if I continue.

Update Day 3

Aussie Dogs Laying 3rd Favourite System

Not looking very good I'm afraid and I may not continue this. Only 3 dogs were matched today/tonight for 2 winning lays and 1 losing lay.

I must add though that in the 10 days of total testing including the 7 of simulated bets the system IS up +29.52 for 60c lay bets (with commission deducted too). It just really gives me the ********s when everything goes hunky dory when testing but as soon as the money goes on the ********ing thing blows up in my face FFS.

What I'm looking for is a mechanical system on the greyhounds that just works but I don't think that animal exists (nor for horse racing either).

The other problem with the Aus dogs is that Betfair doesn't have that much volume. Ideally, if I could find something that works, I would like to upscale it but the volume isn't really there. Maybe on the first fav but not on the rest of the dogs.
