Of course it fits the definition of the word ‘noticeable’.So you got 6% more charge in the same time, which is ~12% faster. (That seems noticeable to me.)
What it didn’t do was have a ‘noticeable difference to my schedule’.
12% of 15 minutes is 1.8 minutes.
Takeaway being on my SR+ it charged above 145kw for such a brief period and during such a low state of charge that when comparing v2 and v3, most people will not have their wait times affected by more than 2 minutes.
