This isn't exactly the answer to your question P57 but it spits out of a program I wrote for amusement a while ago so it's easy.

Betting on the favorite over many years at WA
You get 88.77% of your money back from the bookie over 16000 races and 97.44% from Tabcorp (33.5% winners). This includes a lot of piddling races at minor courses, thus, I guess, the high return from tab favorites. - From NSW Tab you get 93.22% from 8750 races (31.5% winners) in the same period (these would be the more major races of course).

Always backing the winner on these same 16000 races - 613% from SP and 793% from Tabcorp.
Betting on the first horse in alphabetical order 62.7% from SP and 79% from Tabcorp.

This is probably not typical Australia wide, I have long suspected SP pays worse in comparison to TAB in WA than it does in say NSW.

I could probably do the same for NSW but would have to do a bit of programming.

Thanks KV. That's exactly what I was after. Makes it pretty clear that on favs or IN GENERAL, the tote is better. I already knew this for longshots as I've many times got three times the odds on the TAB ($60 for a 20-1 bookie quoted horse etc).Thanks again. P57

Hi Benny,
Heres a simple way of pricing your 4-5 selections per race.

Divide the number of career wins into its career starts.
e.g. 4 wins from 21 starts =5.25/1 or $6.25
e.g. 2 wins from 4 starts = 2/1 or $3.00

This only works where all 4-5 of your selections have had one or more career wins, so its probably best to pass up any race that does not qualify under those said conditions

I hope its all right to post this site , it has a priceing program in there that may be of some use to you.

Bhagwan,

I don't mean to be pedantic but isn't 2wins from 4 starts - 50% or 1-1 even money, which is $2.00.
2-1 means 1 chance in 3 or 1win from 3 starts.
