Hi, L.G.

I don't really have answers for your three questions, all I can give is my opinion/experience.

a) I'm currently working on a Place system. One of the rules is that the selection must be placed at it's last start. There's been 11 days of real betting for 36 placegetters from 47 selections for a 28% POT (my TAB account is smiling). I've also applied the system rules to those selections that were unplaced at their last start, and the results are "in the red".

b) Unknown

c) Also unknown. However out of curiousity I often look around midday at the TAB prices of most of my lay selections, and because of their prices (one or two have even been faves) makes me feel somewhat uneasy because I think my ratings are out of whack. However with more money in the pool they ease to become an outsider. I can't remember if the reverse in the price scenario has happened to any of them.
