Fair enough, was just throwing that question out there.
I tend to use them for max values, status lookup codes, days of week, months of year, etc. Mostly for program readability. I tend to use them in a compare statement. IF (UserDefinedSetpoint < MaxValueSetpoint, UserDefinedSetpoint, MaxValueSetpoint)
The other day I was trying to analyze a series of calculations and found myself going back and forth between the Documentation Editor and a Data View to see all the values involved, when it would have been nice to line them all up in a logical order in a single Data View.
I do like how they show in a Trend View, as they can be added retroactively and they populate data all the way back to beginning of data set.
