How To Know When Your Betting System Is Working (or not!)
I really enjoyed your talk last night. Would it be possible to give the formulas for creating AE and Chi Squared here, please?
The A/E is:
actual winners / expected winners
Expected winners for each horse is:
1 / Betfair SP
Add the results of all this together for all the horses.
The Chi2 is:
=chitest(Winner:Losers,Expected Winners:Expected Losers)
