For the life of me I can't understand what you are getting at Peter. You seem to want all the favourites to win and the exotics to pay the smallest dividends.
I can't understand this because that is exactly the situation in which the punters are at the greatest disadvantage in terms of roundings - when the favourites win, when the most units are on the winner. The TAB absolutely loves favourites winning. If they had their way favourites would win every time because the most profit is taken by the tote when they do.
There was no bloodbath at Mornington last year. I looked it up as soon as you posted it, and even the long shot winner certainly wasn't a hopeless case.
Have you thought about gardening. It is very rewarding, gets you out doors and is good for the soul. I just don't think punting is your thing.
