FWIW, going forward, I think the one transfer rule will make it harder to take advantage of the computer glitch to "morph" points.
I believe the CMs were always trained to make a note of homeresort and use year when points were transferred and that they were told to look for notes when they make reservations. Before the internet became so popular, very few people transferred points and very few knew how the computer system worked. So it really didn't matter much if the CMs missed a note here and there.
Along came multiple transfers - not sure why
DVC ever allowed multiple transfers at all, but they did. The internet publicized the "glitch" and commercial renting became an issue.
When transfers were unlmited, it must have been an impossible, very time consuming task to look for the notes, so few CMs took the time - gotta answer those calls! Anyone who has seen what the activity reports look like will know what a job that must have been. I think it even became acceptable for the CMs to not even bother to check.
However, I think since DVC sent out the "no commercial renting and one transfer per use year" email, that training (look for the notes) has been re-emphasized. I think most CMs will now e looking for transfer notes - they'll be a lot easier to deal with now that there can only be one per use year.
I think DVC "fixed" the "morphing problem" by telling the CMs to make notes of home resort and use year when transferign points. I think they have reinforced the traing that says the CMs are to look for the notes before making reservations.
Obviously, this is speculation on my part. But it is probably cheaper to fix the problem with training than it is with software - at least in the short term. Limiting the transfers made the manual "fix" feasible. I don't think anyone should count on the ability to "morph" points.
