And YES - I did want him to give me (and the rest of the world) a foolproof horse racing winning system.
there is nothing fool proof but there are definitely systems out there - Im testing one with a work colleague based on an idea I had after being introduced to someone else who works in the industry.
as an example - arbs are still possible though occur less frequency as every man and his dog has a betfair bot
there is also, so Ive been told, a satellite channel that offers a quicker news feed to some foreign races + some punters have laptops trackside and take advantaged of a slight broadcast delay to lay horses that fall on betfair
others have developed neural networks to make predictions with varying success.
my system exploits another tradeable but slightly more subtle edge which should leave me with a flat position + profit before the race even starts.
