Have been working solely with rules and have now created an overall rule flow 
that has enabled me to eliminate parts of the conditions of many rules, because 
the rules are in rule flow groups.  For example, if the glucose value must be 
below 40 to get into a rule flow group called "Below 40", then I do not need to 
check that the glucose is below 40 in the condition of every rule in the group.

I have noticed, however, that when a fact is inserted, it appears to activate 
all rules for which the conditions match, even though the majority of the rules 
are not in the rule flow group.  I am interpreting this as simply activating 
everything applicable, taking advantage of the Rete, and then the activated 
rules are filtered by rule flow group.  Is this a correct interpretation?

The corollary question is whether I am using best practice by eliminating 
"redundant" conditions from my rules, or whether I should include in those 
conditions the constraints that were determining whether the rule flow group 
becomes active.  If this scaled up to one to two thousand rules, would the 
activations and filtering be more costly?

Thanks for any advice.  My colleagues and I were very happy to eliminate the 
redundant conditions because it makes our rules look simpler, but now concerned 
may be going down wrong track.
