Does anyone review their systems after Spring, Autumn or Winter Carnivals and see how they have performed against the rest of the year? Obviously it will depend on the systems we work with but with so many good/great horses returning (47 first up from a spell at Flemington tomorrow and another 39 that have had only 1 start from a spell) does the strike rate take a hit?

Over the past 3 weeks (Saturday - A,B,M&S) the winners for a system I run have fallen from 12 to 8 to 7 (over 32 races). Should I expect another drop tomorrow?

Any thoughts?
