ETA for nuvis: they do learn a user's habits and adjust ETA

Greetings,
I've seen this discussed a lot in the past but never read this answer before. It now appears that nuvis (at least some models, I guess) do monitor and learn a user's typical speed in the various speed categories of roads travelled, and over time, this training will adjust ETA times and make them more accurate:

Hmm, I wonder if those folks reporting wildy erroneous ETAs have recently used their nuvi to trace a route while travelling by air.
As mentioned in the link above, it's surprising that Garmin hasn't used this in their advertising.
I see now
I was wondering why after three weeks of ownership I have not been able to significantly "beat" the 880's initial, pre-drive ETA. Here in Atlanta traffic usually drives a minimum of 5-10 MPH over the speed limit. Over a long distance I knew that I should noticeably improve upon an initial ETA generated solely by posted MPH.
But that was not the case. The Garmin is usually within 1-3 minutes of original ETA even on long trips with stop lights. I understand why now.
Thanks for the information.

Update
The Nuvi regularly updates the estimated arrival time based on your current location when you reach various waypoints in your trip.

Yes, but that's not what's being described here.
Self-learning??
I knd of wondered this myself. My Nuvi 350, when I first used it, would try to take me to work going the wrong way on one-way streets; but after a couple trips going the correct way, it takes me around the right way.
