it sounds like
absolute cod fillet to me (thats bad). punters, be they online, in a shop or at the track cannot pick winners regularly enough to make it pay simply by following odds.
there is a big case for multiple staking on one race however, but you almost have to forget the odds completely to make any system work, as in time its the largest BF prices thatll swing things in your favor.
in a typical graded race, youd be looking for the fastest 2-3 trappers in the field, if theres an inside runner thats likely to go for the rail then all the better. what you want is for the dogs that are potentially fast enough to get to the leaders to take a few knocks on the first bend, then all bets are off.
typically ill only back a race if theres a clear early advantage to two runners, who also have proven in trials or lower grades that they are capable of a time with a clear run. if theres a single danger in the race, that is a consistently fast wide runner/stayer who can roll with the punches then i leave the race completely. if theres others in the race who can compete with a clear run then i may still go for the trappers, especially if the dangers are on the outside.
ALL SAID, i lay 'em

might even start a topic to track my progress as the dogs are by far my biggest profit on
betfair, up about 80 on the horses (football im down about 4 million and ice hockey im down 13p, which i wouldve been using to get free bets matched!).
i can keep track of dogs within
betfair but itd be good for this site to maybe get a decent dogs thread on the go. the best greyhound forums online are on
betfair and dailydogs.co.uk, both have severely gone downhill recently, even with the huge meeting at hove this weekend coming up.
