I'm quite certain a law was enacted here in NSW in the '70's that if your selection won then you had to show a profit.

However that does not excuse the way divvies here are calculated. A 50 cent divvy is originally assumed and then rounded down by a multiple of 10 cents. It is now doubled for the declared divvy.

For example, a 50 cent winning ticket after the TAB 15% (approx) might pay a true $0.99 but is then rounded down to $0.90, instead of $0.95. The $0.90 is then doubled to $1.80 which is the divvy declared by the TAB.

Yet if it was calulated on a $1 basis, the true divvy would be $1.98 which is then rounded down to $1.90 - not the TAB's declared divvy of $1.80. The smaller the divvy then generally the greater profit percentagewise for the TAB. In reality, many of the $1.04 divvies should pay $1.10, approx half of the $1.10 divvies should pay $1.20, etc.

I am under the strong impression the other TABs do not calculate their divvies using this method?
