[rules-users] decision and prediction based on the same set of rules

[Sean Su]

I agree with your points, Steve.

I know this solution will require certain "statements" on the RHS which I
am trying to avoid due to the fact that the "business team" is authorizing
the rules. But I will keep that as an option.

Thanks

Sean
