How much power he puts into charging it isn't the concern in degrading it is loss of range. I know how old lead acid batteries can charge all day at some high amperage and they still are junk, or vice versa chargers shows they tapered off to low amps and the battery has little capacity to keep it's charge or start the car on a cold day. Kilowatts into it is same as old school amp charger experience just different terminology. amps times volts equals watts.
All in all his and comments have similarity to what many owners have said of batteries doing downhill fast or requiring replacement are not that common. Other problems not frequent. Dealer service often disappoints. Brakes last forever. Supercharging doesn't ruin them. Tires last according to driving habbits and can be replaced with cheaper options but with higher rolling resistance and no interior foam sound proofing liner.
Acceleration per dollar -used model 3performance I have been saying it many times here so I won't belabor it.

I didn’t call it out because he used the same methods consistently so he was basically reporting the difference in his experience from early in his ownership to later in his ownership. Now, if he said “I’m an engineer and I have studied my battery degradation” I’d make the same call you did.

And as ChevyRules said, depletion characteristics are much different lead iron to lithium ion.
