To emphasise the points i made earlier, refer to race 5 Sydney today(27.1.03 7strs):
No.1 Spillway won paid NSW $2.90win $1.90pl
This emphasises my point about betting the place in small fields. Although Spillway was the favourite it presented an opportunity for an overlay bet for the place.ie $2.90 win in a field of 7 strs, you would expect the place div to be 1/3 win odds, ie $1.90 x 1/3=$0.63, rounded down to $0.60(+ $1 investment = anticipated place div of $1.60, yet punters were able to secure $1.90, $2.00 on Supertab, representing an overlay of 18.75%, even better on Supertab, a pretty respectable overlay I'm sure you would agree?
