> Are the data sensible after, say 3500 rules are run? If each rule is a separate unit of work and you do not require all rules to be run for the data to be ready for further use, then it might be understandable with many transactions.

Yes this is the case - as each rule finishes the outcome should be live/active to the rest of the system. Also, almost as soon as rule 6000 finishes, it will start again with rule 1. It takes 3-10 minutes to run through 6000 rules.
