Heres a staking plan for someone that likes to bet aggresively, and for a bit of fun. I have used this for place betting the last week or so, and am averaging a profit of 1.5 units a race. Chances are its gonna fall over sooner or later, but is good fun. Keep betting up the series until in profit.

I added the single unit bets at the start to try and protect it from a bad loosing run. If at any stage a profit is shown, rule off and start again. Once you are into the prgression, a divi of around $2.60 clears the series. Some of the profit can be quite good especially if you get a couple of smaller divis which bring it close to even, then snag a nice $2+ divi to kick it into profit. So it pays to use a method that occasinally snages a $2+ divi, although even using smaller ones, a good run of three of four will see it make money.
The other thing is that even if you get to the last bet, chances are it wont be a total bank wipeout, unless you were unfortunate enough to pick 15 non place getters in a row.

Now we all know that theres no way to turn a loss into a profit so dont bother posting as such. I have been using it on a method which shows a 2% POT, so maybe I am just lucky.

But anyway, have some fun with it.
