I think what you will find is that the average tipsters SR for their top 3 is 46%
But they all have great days & not so great days.

I feel 46%+ is very good .
I have found in the past its better to work with 5-6 tipsters rather than 10 or more for whatever reason.
One tends to hit the better prices this way.
As with 10 & more tends to hit a lot of the shorter prices.

I would suggest breaking the 8 race venue into 2 halves .
4 & 4.

Try & strike a winner within those first 4 then stop.
Now do the same with the final 4 races.

Staking plan 2 2 3 4 = 11 until a winner ,dont go any further start again .
Or 3 3 3 3 = 12 level stakes.


For 2 horses a race bet 3 + 2 = 5
This is equal to 60% + 40% this works well on the right selections especially if there is a juicy price with a short priced commodity.
It gives a punter a lot more confidence in his betting if the prices look right.

Place the $2 on the longer price of the 2 horses or visa vera for value hunting & $3 on the other.
e.g. if the 2.50 shot looks like he is drifting in the market & has a chance of losing & one of your other chances is paying $14 , one would feel more confident having a crack at the $14 shot knowing one is covered with short priced Fav.
If the $2.50 wins x 2 ret $5
If the $14.00 wins x 3 ret $42

I feel you will be a lot more successful if you can break it down like this stopping at the first winner in 4, long term.

Do the same for the other venues.

Cheers.
