Bagman,

Had a look at that link. Unless I missed an operational option, useful but not for framing our own market. If I enter odds on offer or PP odds all it does is tell me % etc. and how much the take on top is. I thought the idea was to frame a market based on our own handicapping, so we can work out if the prices on offer are underlays or overlays according to what WE think is a fair price for our runners?

Pricing the whole field [100%], unless you want to create race meeting ratings, seems a bit of a waste of time when ratings are available all over the place. Why bother, when we are only considering 5 or 6 runners [80% of winners are in the first 5 PP odds runners] anyway. If we think every horse has a good chance of winning, we shouldn't be betting the race [unless it's the Melb. Cup].
