Appreciate the comments, guys. That's exactly what I was hoping for. I realise there are many other factors to take into consideration before one has a "system"! However the results I referred to yesterday, the earlier comments of six or eight months back, and the generally supportive comments of you guys, at least give one hope

Specifically:

Michaelg, those figures are most encouraging. Will have to learn more about BAT. Thanks.

Mark, in fact, I just presumed the final Unitab price (going back over the results on that site). I realise decisions have to be made about all the things you mention -- and even then, they are sometimes thrown out by last minute scratchings or other hold ups (to use only one example).

I think I would tend to use the prices on the TAB. As you would realise the Betfair prices are often different. In one sense I don't see that it matters if they drift out or firm. The old "swings and roundabouts" conundrum! But you are right. All these matters have to be addressed.

Bhagwan, appreciate the thoughts you have put down. I agree decisions have to made about the races one follows. In the last at Taree yesterday there were (Unitab) 5 horses out of 11 starters in the band. Not a proposition for me --- and one of them won! (By the way, your typing must be a lot better than mine. This is taking me ages and your reply, generously, was three or four times longer ). Thanks.

And, Chrome, your comments are appreciated. Its just that laying seems more attractive (despite the disadvantages you mention) especially on days that are full of "rubbish" races. I know, I know, one shouldn't bet on such days, but.............Always respect your posts.
