... although it's potentially a bit complicated due to the differences in market% due to field size when betting for the place. Ideally you'd be recording the market% of each race and normalise each selection individually, then aggregate the totals instead of using the average SP.

What the result is saying is that to this point it's very unlikely that what you've observed is due to luck. It's a tool, not a guarantee that things will continue along the same path, and assumes that the SP is an accurate indication of a selections chance.
