Hi!
I ran some tests over the past results re. favoreds winning and losing by staking.
Found some interesting facts.
Stands to reason that level stakes bets are losing.

If you multiply your successive bets (after losing) by less then ~1.6 you will still lose!

Now this number will change with strike rate and avg. odds and only applies to TAB favs.'s strike rate and return.

If you multiply your bets over the 1.6 mark, in the end you will win, BUT you can be down as much as -$751.00 and your next bet is $450.00 (this is on a 1 unit base one month only)

If you go to double your bets after losing, it becomes impractical because the losses can be huge, and the largest bet to recover, be over $16000.
It would ruin the odds, even on a Saturday, and placing it with other than the TAB well nigh impossible.

So there you go folks, if you are game enough and want to have a go at the favs. and have plenty of money to tie you over, keep in mind that magic "1.6" multiplier.
It's a fine line between trying to win more and able to finance it.
I personally can't recommend it, the risks are just too great.
