Racing system - 6 steps to heaven or hell?

Does anyone remember that free All Weather system that RSB (Racing System Builder)used to include in their free starter pack?

Shown below is an All Weather system that I've constructed (aka backfitted) today. Additional rules have been shamelessly added to increase profitability. Each new rule has been highlighted and below each step is the resultant profit figure after the latest rule has been applied.

The system runs from November to March and I fully expect it will have gone mammaries up by the time we put the clocks forward next year. I'll keep you posted.

Sadly, or perhaps fortuitously, there are no qualifiers today.
