Back Fitting Of Horse Racing Systems

The term back fitting when applied to horse racing systems
can be summarised as over engineering selection criteria
putting all logic and common sense aside in order to produce
what on paper looks to be a profitable historic approach.

The big danger in doing so is that non sensible criteria are likely to
lead to future losses even if researched history shows positive results.

Who Can Fall Prey To Back Fitting?

You perhaps :)

If you research your own systems it is important to try and think logically.
Are there good reasons why your selection criteria are likely to produce good results?
Be careful not to use silly criteria just because by random fluke
the monkeys with type writers of historical results scatter happen to show some positive results.

If you buy systems from a system vendor tread carefully too.
Remember the seller is often primarily concerned with making a quick buck from you.
Often what he cares about is putting up a big sexy past profits pound sign in front of your nose.
They want your cash today and care little about whether what they have sold you with a pile of hype
has significant chance of doing well in the future.
