Have been playing with a system that has shown some great results so far, so have been lookig at a few of the tests that can be done to see if the results are luck or not. Now, I grabbed this chi test from an old post that angry pixie put up.

Can someone check that I have done this right? As I intend using betfair, for normalising the market I used 107%, as the markets generally run at around 102%, plus then adding on 5% for commission (not sure if thats a correct way to do it or not?)

Here are the results to date.

System base stats:
Bets:176
Winners:46
SR:26.7
Av div:4.94 (betfair)
Av div:4.33 (supertab)

And my attempt at the calculations:

Observed wins:47
Observed loss:129
expected wins:33.2
expected loss:142.7

Chitest result: 0.008374369

Running the same calcs for the TAB divvy I get:

Observed wins:47
Observed loss:129
expected wins:38.74
expected loss:137.26

chitest result:0.132905506


So if my calcs are correct, that would suggest that the chance that the results are down to luck is 0.8% (betfair), and 13.2%(tab)?

Could one of the gurus check if these are correct?

Cheers
