No offense intended. I am going on a twenty five year old memory here. My recollection is that it started as a very small, relatively elite event. Then it was rerouted to take in all five boroughs and it became a big event.
If my memory is correct, you are comparing apples and oranges (no pun intended). Also note that the median time went up 40 minutes from one year to the next. That must reflect the change I described above, since it is way too big to be random or measure an incremental annual change.
It would not be reasonable to compare the NYC marathon with the US Olympic qualifier, an invitation only event, for example. I don't think it was that extreme, but my memory says you are comparing events that were the same in name only.
Correct me if I am wrong.
