A retest of a very good lithium AAA battery, has it change performance during the years (I tested it in 2013)?

The discharge curves looks normal for Lithium batteries, i.e. constant capacity also at high load. This battery holds capacity up to 1A current.

Conclusion
it is still a very good lithium battery, in fact it is slightly better at high loads, but capacity is the same.

Thank you for the review, thorough as ever.
I noticed that Energizer now claims a shelf-life of 20yr. (on the battery itself: 12-2039).

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.
