I used to think the same, but now I've driven 35k miles I can see the variations of the range and can correlate the events leading to them.
The best explanation I found was this.
The range is calculated by the battery management system (BMS), it uses information from each charge session to estimate what range that works out to. But as we rarely charge to 100% it has to extrapolate based on the charges you do perform.
Its a bit like figuring out how big a gas tank is, but only using the amount of the last 10 fill ups with none of them being more than 30% of the total capacity.
So if you have lots of small charge sessions it really skews the numbers.
I saw that when I left my car at the airport where they would plug and unplug based on the number of other EVs. Lots of 2-3% charging sessions and my range dropped 5 miles.
Last week I did a series of 120-150 mile drives and charged back to 80% - my range has been creeping up and is now back up to 304.
Yeah, I definitely think it holds weight. I've seen slight decreases in rated miles when charging more frequently for smaller outings, and then saw some increases letting the car sit at lower SoC before charging back to 90%.
