Changing score by negative scoring
A smart campaign qualifies people if the score changes to more than 99
Some records qualify for this smart campaign when their score is decreased by 25
We realize that even if the score change by "-25", it still qualifies for Score is Changed, and because the total score after "-25" is still above 99, they qualify for this smart campaign which MQLs people.
Hence, we try to apply the Change Constraint. It doesn't work.

So we resort to the option to define Previous Value, New Value, Data Value Changes - it works.

This whole thing looks pretty volatile - is there anything similar you have experienced before, or if there is a better way to resolve this?
Thanks!
