Given the average field size and takeout%, we can project what should be the average winning odds.
AveWinOdds = (FieldSize*(1-Takeout))-1
So, 10-horse fields with no takeout should average 9.0 win odds, and 10-horse fields with 20% take should average 7.0 win odds.
Using the same formula, we can extrapolate the total rake (or projected takeout) using actual win odds and fieldsizes and determine the "Rake and Take" difference.
Takeout = 1-((AveWinOdds+1)/FieldSize)
or for our purposes,
TotalRake = 1-((AveWinOdds+1)/FieldSize)

Presuming all the math is right, the chart below shows Total Rake, Track Takeout, and difference.

Inflated Rake is result of winning underlays (or returns below expected).

THIS CHART IS COMPILED FROM THE YEAR 2020. SAMPLE SIZES BELOW 200 RACES SHOULD BE VIEWED DISCRIMINATELY.
