The "science" of guess-timating transportation times is extremely imprecise, to say the least. Some measure from the moment one steps onto the conveyence to the time one steps off. Others will factor in their wait times. Still others add in time spent walking to/from the transportation depots as part of the trip. I suspect many don't measure at all but simply go with a general "That wasn't bad" or "That was horrible" perception. All of these conflicting methods contribute to the confusion whenever the topic arises.
As crisi mentioned, if you have a "magical" trip where every bus/boat/monorail is pulling in just as you arrive, your perception of that resort will be that the transportation is fabulous. On the other hand, if your ride seems to always be pulling out just as you arrive and you have to wait for the next one, your enthusiasm for the transportation at that resort will be tempered somewhat.
Of course, neither of these scenarios is the norm, but they do happen and people without a lot of experience at a resort tend to assume this is what they can expect, good or bad, on future trips. The reality lies somewhere in between. Sometimes it's a fairly short trip & sometimes it's not. I don't expect AKV will be any different in this respect than any of the other DVCs.
