I can tell you the average divs of the winners and the result of backing each $10 flat stakes @ TAB prices...

Just 100 Raters
Avg Div = $3.74
TAB Prices = -$45 145

100 Rater + Tob 4 Tab Tips
Avg Div = $3.17
TAB Prices = -$33 159

100 Rater + Tob 3 Tab Tips
Avg Div = $3.07
TAB Prices = -$30 305

100 Rater + Tob 2 Tab Tips
Avg Div = $2.87
TAB Prices = -$22 078

100 Rater + Tob 1 Tab Tips
Avg Div = $2.58
TAB Prices = -$13 713

So yeah they don't make money just like that (well not with TAB prices).
