Star, your comments are right at the heart of what I wanted from this thread. In my original post I said ..... "A key feature of having a successful system is your ability to understand why it performs as it does, including both good and bad results, and accepting that luck plays it's part too."

You've accepted that you need to do some forensic research to find out why your short priced horses are failing and I agree 100%. Make an allowance for luck, as it does play a role in racing. Do your research without any of your long held beliefs clouding your research. Go into this with an open mind Star. It may be that you've set up a filter based on a mis-conception or a myth, or a long held belief ..... ??

If you find out why your short priced horses are failing then you're on a winner aren't you ?? So the stakes are pretty high. Good luck !!
