Thanks for the reply, Angel. I agree that it is up to the individual to decide his/her level of comfort.

Actually, I said that the bet is not reducing --- so you would have a full $10.00 on the winner. You also have to consider that, with the progression, it is not only the $140 that you risk --- you have already outlaid $260 (as against the even stakes betting outlay previously of $70). You would still be well ahead ($720 versus square on a $7.00 winner --- but they are not too common --- though a couple this week), but in reality you have $400 riding on that last bet! If the bet came in at $3.00 (more likely), you would have actually lost $20.00 on the series!! Good fun playing with figures, isn't it?!?

According to my calculations four bets today (before scratchings): Nowra Races 2 & 5, Swan Hill 6, Grafton 7. Dubious about heavy or slow tracks though.
