whilst it makes sense that on average wet track events will have fewer runners & therefore the favoured runners more likely to win, it doesnt explain why average fav sp would be higher, one would expect the opposite i would have thought

perhaps with wet tracks there is generally a lack of confidence in betting markets & the books have got to get a bit generous to get the cash out of the wallets, & less bookie money being layed off on the tote means better prices for all? duno
