Greening according to IP

[seaspaniel]

I'm struggling with the maths on this one.

Is there a greening function in which the amount greened reflects the implied probabilities/odds? In the long term is the expected return increased. Or is a flat greening the most efficient statistically. It is certainly the easiest but is it the best?

My conjecture is that as the market is efficient so a weighted average return is better than a flat return.

Initially I thought this was just adding gambling into the trading mix but the more I thought about it, the more I thought it was just using additional market information to improve average returns.

I think this might be associated with the Dutching/Bookmaking functionality where the returns can be adjusted
