Well, you did the most important thing Mickey - you conveyed the very correct point that you lose a lot of EV if you use FPDW's strategy on Ugly Ducks. Almost a percentage point deduction is huge.
As an aside, if you didn't already know, you can have the FVP software substitute an entire strategy chart (swap out the Ugly Ducks strategy chart and replace it with FPDW's strategy chart and, of course then run it against the Ugly Ducks paytable) rather than deleting a strategy line of the chart or moving a strategy line to a higher or lower rank in the chart (which of course is a very valuable feature as well) .
As powerful as FVP is, what's amazing is that Wolf Video Poker is even stronger still - significantly so. Too bad Jim made the software protection such that if your hard drive crashes, you lose access to the unlocked software since the software activation page is long gone.
