Hi Chrome and very interesting, you have me intrigued here. A couple of silly questions here as I am not a Betfair person. These horses that open at less than $1.55, can you back them early or do you need to be sitting at your computer at jump time. It is our bedtime when its afternoon in the UK. And I guess your profit margins are very slim in some cases, meaning to win 20% on turnover with a strike rate of 70% you would have to be getting at least $1.75 on every one of your 7 winners from 10 bets. Not sure what the commission is that you then lose.

I'll check this Ladbrokes site out, just for a sticky, all very interesting stuff here.
