Hi Topsy,
Very interesting concept you have here.
If you have two in a race you say you back the highest odds,if they are both good odds have you worked out over a period backing both,e.g profit loss as to backing one.
Per example R6 SYD yesterday,What an enormous E/W bet backing both,basically 6 chances in 14 to get a profit and if one of them saluted!!!!!!!!!!

Cheers
