What I said is there is currently no evidence of abnormal degradation related to charging habits thus far in the Tesla fleet.
Well to some of us, that's like saying: "I feed my 5 year old dog cheap dog food and he looks just as healthy as your 5 year old dog". It means nothing to us since we know it's not until later years that the effects will start to show -- the principle is the same with these batteries.
This is also aside from the fact that what you say you said above is not what you said. You said:
Honestly, I have seen no compelling evidence that charging to "X" percentage has any effect on the battery life, positive or negative.
The Tesloop car I was talking about in particular has 200k miles on it.
We know from the science that age means more than miles, and this is even pointed out to you:
Even if there is a difference, you won't see it for a while. If there is a difference, it'll start to show itself roughly two thirds of the way through your battery pack's lifespan, and you'll see an increase in the rate of degradation. It's referenced as a "knee" in battery capacity fade.

You expect the "knee" in battery capacity to show up now, when the oldest Model S is only 5 years old, and you try to say that additional miles counts for time, when the studies show otherwise.
