Well, today UP only increases by whole levels, so it behaves as an item and Item Gain is appropriate. This is what most current code use for this quality anyway.

Now, historically (i.e. before SMEN went on a long hiatus and returned), UP used to progress by CP. So old (retired) SMEN pages might indeed use Increase for UP, and I think it's fine to leave those as is.

On a similar note, I'm wondering myself about the Intimate with a Secular Missionary (both Item Gain and Increase used by different pages) and Intimate with a Revolutionary Firebrand (using only Increase) qualities. I can't remember if these increase only by whole levels or sometimes by CP (most -- but not all -- uses of Increase for these are using the "to" param to explicitly specify the new level, which is the correct usage, if it can be done consistently for all occurrences).
