Hi Mattio,
I feel you are taking the right approach by using multiple lay plans.
Just make sure that one does not double up the bet when there is 2 or more selecting the same Horse.
Because it does not mean that it has twice the chance of falling over.


Coming back to your original question as to what the SR of winners would be , the general answer is approx 20%

I think you will find it rather challenging, long term to get it much lower than that 20%.

The general SR of Favs is 30%
Take out all the odds-on shots <=2.00 & its 25%.

Here is an exercise you may like to try .
Grab 10 lots of 10 races in any order = 100 races
Get 10 of your mates to select just 2 Horses to fall over from those 10

I can almost guarantee that it will average out that 2 from 10 will still win instead of lose = 20% win SR

Its amazing how many can win in spite of terrible form or barrier draws ect,.

If you can secure only 20% winning at a max price of 4.00
Then that leaves us with an acceptable profit of 20%+ POT.

You now laughing like a Hyena.
