I'm the OP. Took the car to a Subaru Tech yesterday. They drove it. Confirms there is a difference in what a new vehicle would exhibit in terms of launch characteristics and (fake) shift points. Said CVT does indeed learn, and factored my extreme event into the moving average. Strange that one outlier like that should be allowed to have such an effect, but it did. Maybe that event is statistically weighted differently. Tech also indicated he's seen complaints like this before when two family members use the car, the wife brings it in saying, its different after my husband drove it awhile. Not sure I like the notion of "adaptive transmission" Subaru should keep it predictable, and add a drive mode if a change-up is desired. Could reset it, but likely will end up back where it now is. Thx for feedback.
