Reliable sample size

Hi Guys,

Could anyone give me an indication as to what they would consider a good sample size is to know whether a betting system is reliable please?

Are we talking 100s or 1000s of races?

Thanks

TB

I would say a month's testing.

Thanks Oxa,

I have used historical data going back 7 months does that count?

It counts well enough to give it a try, but there is always a chance that something will go against the trend.

Plus read this to be on the safe side.

The number of race is Exponentially proportional to the odds.

I am still to find a formula I am happy with myself to work this out.

.. some like
odds Races
2.00 20
5.00 60
10.00 200
50.00 2000
100 5000

Thanks 1oser,

Essentially, i have been looking at tipsters. And I have noticed that certain tipsters do well in certain price ranges but i didn't know what a good sample was.

Some are in the range of 100 -200 races but others are in the 400 - 500 range and still showing a good profit.

Is that enough?

The only problem is that you do not know the selection method. Sample size is dependent on same and consistent method of making selections.

Start small is my recommendation.
