Interesting stuff Mark.
I'd like to play Devil's Advocate if you don't mind.
I'd also like to preface it with the statement that I know what you do works and has done for many years.
a) isn't this similar to laying to liability rather than payout because of the staking?
b) I notice that the staking is only a sideline, the actual knack is getting the market percentage to 102.68% in the Oakleigh Plate example.
This is not an easy task for most people, because the odds are always floating.
c) Have you noticed the chances of getting good market percentages shrinking over the last 6 months?
d) What do you do with odds on favourites, do you lay them all, lay them selectively or ignore them completely?
As you know I have been laying the field for a few years, and the penalty is the rollercoaster when using Betfair SP liability.
I think I have solved that portion of it.
I'll expand on this later, but this is your spotlight
Well done.
