thank you

I looked at this today and decided on identifying all the horses in each race which were unders according to fixed prices or all three totes.

I then picked one horse to lay from those. I stuck to the les than $30 range.

So far its done well with 18 selections for no winners and the odds I am laying at are generally a lot less then the final betfair price (could trade out of them) and in some cases lower then all 3 totes.
