on a method that is showing a poor A/E + a loss to both SP & Betfair should have such a high CHI numbe
 
Someone else will be able to describe it better, but as I understand it the chi score is merely an indication of how likely the results are to be representative of the method rather than just down to chance.
 
The sample size is large which is a component of chi, so makes sense it would be high.

As has been mentioned elsewhere though it's predominantly a mathematical formula based on the numbers involved, it doesn't analyse the logic involved (or not) and it's entirely possible to achieve a very high A/E, chi score etc with a heavily backfitted, flawed system. Still a helpful metric though
