Well, It is true I have never heard of it before this. At least you had the brains to actually provide us with a little background info on where you are coming from.

From what I do know, most companies list the number of weeks for your variety to be "Commercially Viable," which basically means "sellable." It has been my experience that by leaving the 'fruit on the vine' for 1-2 weeks longer than is usually suggested will improve on the creation and accumulation of a diverse and varied range of different cannibinoids than you would have had at "Recommended Harvest Date." Since a quick turnaround is a good selling point, companies tend to list the fastest possible harvest. It is also an old grower rule of thumb to wait a week once you think they are ready. Similar reasoning is involved with this as well. There may be more to it than just this, but what I am talking about applies to all cannabis plants, no matter how long they are vegged for. It is possible that also using a very short vegging period could also effect this. I am going to do a relatively short veg period on an indoor harvest, but all parent plants are gonna be vegged at least all summer, so I can compare the ones I let veg all summer to the ones that had an 8 week or so veg.
