Thanks for that, Chrome.

Out of interest, Toulouse Lautrecs' final Place trade on Betfair was $1.21 yet it paid $1.04 on NSW TAB. I've found in almost every case that the lower the TAB Place divvy the greater advantage percentagewise using Betfair. The greatest I've seen was TAB $1.04 yet $1.31 (5% take-out not included) with Betfair.

It's Betfair for me now with this method which generally selects very short-priced horses, and your figures show it should be profitable.

I forgot to mention that if a selection has won its last three starts then it becomes a non-selection.
