A losing result backing 4-12-12-12 according to rated order. Ratings for me came in at 12-9-7-8 so nowhere near it really.
I think there is an optimum field size for first fours. The bigger fields (18+ or so) often don't have sufficient in the pool to cover paying on all combinations. Hence you could back the field in a field of 18 (118 440 combinations), the absolute outsiders could get up and you'd be paid out at the approximate pool size (30-40K) which would be gross unders.
I think that a 'working' size for first 4s is around 12 to 14 starters. Next step is to find such a race which promises to throw up an above average priced set of placegetters (maybe a race with 5+ [or so] horses 1st and 2nd up in it). Anyway, food for thought. Anyone interested in contributing, I'll nominate a race on Friday and allow until midday for your thoughts. That way I should be able to work out the concensus ratings by approx. 1pm.
