You still mistake the loop offset for that end result you so vaguely

You've conveniently snipped those numbers so you can make it look like
none were provided.

I gave you the statistics you've asked for and are now ignoring. I
simply don't run ntpviz.

You might want to read a whitepaper or book on how crystals age, there
is a choice of more than a handful you can just download, from all the
usual suspects. Or maybe you don't want and keep your opinion. Either
way is fine with me.
For your convenience, NIST defines "Aging is the systematic change in
frequency with time due to internal changes in the oscillator." (that
was proposed to become an IEEE standard in 1992).
What you're seeing here is most likely caused by stress relaxation
(thermal hysteresis), since the long-term aging actually goes the other
