I stumbled across the Propun website and was intrigued by the stats there enough to see if it would be possible to make a buck out of it. After a few calcs with the spreadsheet I came up with the following:

The information on the website leads one to believe that with a bit of effort one may be able to consistently increase ones bank by 5% per month (give or take a couple) using the tips from the service. However common sense says that I would not be able to do that at infinitum because we would be winning so much money after a few years we could buy out Microsoft . Somewhere the service and ones' betting skill would have to provide a series of loosing months whereby the bank got severely 'busted' and destroy the illusion of buying out bill gates. So as far as systems are concerned, no staking system will work if the selections are crap, so the only hope is to get 'inside' knowledge as provided by the ProPun service or someone who has the inside word at the track. As far as I can deduce, the only hope to win in the long run is the consistent quality of selections; whether by inside info or tipping service - Could I interest anybody to pick the eyes out of the above logic?
