Has anyone thought of adopting a Staking Plan based upon the no of runners in a race?
For example if a punter is more successful in races where there are 12-13 runners, bet more on those races.

Punters would have to look at avg profits - combining the effect of strike rates and dividends.

Maybe something like this:

9 runners - 110 units
10 runners - 100 units
11 runners - 85 units
12 runners - 75 units
13 runners - 65 units
14 runners - 60 units
15 runners - 55 units
16 runners - 50 units

But would all depend on avg profits, no doubt they will fluctuate over time, but if the stay within a range, this plan may work ok.
