It’s really a question of contributors. There’s not a lot of debate that the mechanisms you describe likely behave that same way in Tesla batteries. So if you want to optimize they are good guidelines to follow. (It’s likely that high SoC matters - I have 40% capacity loss on an EV battery (GM) that is always kept at 100% - when I have it replaced I will try to find an EVSE that allows me to set a charge limit. But even this is just correlation - not causation. Many of those vehicles are kept at 100% and this is probably a bit worse than most, for example.)Research by battery scientists and referenced at Battery University, for example, quantifies this and is obviously well known and acknowledged. What you say could be true, depending on how you define "significant". I am not trying to change your behavior, nor am I judging it. It is a choice. Accurate information will help new owners make their own choices.
However, the available evidence suggests that other factors by far dominate the capacity loss people see for Teslas. Those factors appear to be:
1) Battery pack lot/date of manufacture
2) Random chance.
3) Use (cycles).
4) Perhaps hot climates/storage.
So you can do everything perfectly and still end up on the low end of the distribution.
We actually just don’t know what dominates. From this thread and tons of anecdotal evidence, it seems to me to be mostly luck. Only Tesla has all the data that would clearly show what are the most important factors though.
