Have a mate who swears by running doubles. He doesn't necessarily take them though, he believes if you take the approximate divvies after the first leg and divide them by the price paid in the first leg, you have a market much more accurate then the win/place pool market. It's weird but reasonabbly logical e.g First leg pays $3 approximate divvy for the doub if number 1 gets the second leg is $12, therefore 12/3 = $4, he backs any horse that is 150% or over this price i.e if number 1 was paying $6 or more he would back it. He believes alot of smart money is involved in doubles as the markets are not well utilised or abused by drunken larrikans just backing the favorite and he goes alright. Its funny he thinks the holy grail of information would be to get the market, amount of money on each horse b4 the first leg. Something to think about.
