Hi,
Just a comment from a newbie re taking the average of 'odds'.
Be careful!
Odds express a ratio and taking a simple average may cause grief.
It is necessary to first convert the odds to a probability, take the average, THEN convert back to the new value 'average odds'.
Example: Average of odds 1.3 and odds 1.5 is 1.39 not 1.4, close so maybe not critical.
Average of odds 2.0 and odds 5.0 is 2.86 not 3.5, not close so could be ruinous!
