losers 240
collect less 5% bf commission $228
payout at unitab sp $186
net profit $42
pot 13%

problem of course is the price layed at, if one can lay at or below unitab sp then ok, if not then 13% doesnt give a lot of room to play with

as to filters -

100 raters losing $16.3
sum of last 3 placings not broken by a spell <=6 losing $11.3
> in weight excluding app claims >=3.0kg losing $7.2

reduced bets to 173
winners 26 - 15%
lifted profit to $75.8
pot 43%

not a lot of action but i would think one could comfortably lay the fav 9 times out of 10 at less than 40% above unitab sp
