CP, every race is different but I'm usually somewhere between liability and payout.
Not the last 6 months no, UK early markets have all but disappeared but that started several years ago. My turnover on Aus races has actually greatly increased over time.
Odds on, if I'm working it's just another race to me. I prefer it when there's a shorty because you've got good % in just one runner, makes making a book that much easier. Black Caviar is a case in point, I held more on each of her last 2 races than I did on all of last Saturday. They also give you a chance at a bigger win with a lower risk.
I'd like to know how you've smoothed the roller coaster if you don't mind emailing me.
As for system hunters (************ts) the last to steal one of my ideas is now out of business....wonder why.

michaelg, yes USA I tread lightly and usually get out when in front.
I do use SP where I can, some races are really good. Rocky R5 just run was 104%, not that I was on. Rightly or wrongly I'm having the afternoon off.

lomaca, appreciate your opinion but I bet it won't change a thing.
