Seems to me like the outliers are the relative few that get lower range.
There should be an increasing number of those though, as the cars' % gauges go progressively further out of calibration, showing less than the true remaining capacity (which shows with a $17 OBD).
I THINK twinturboz is the one who reported a substantial improvement after lowering 2". & I THINK it was "Warriors2727?" who regained about 20 miles by resetting his % gauge. Everyone else who has done so properly has reported similar results, so if range seems low, it's likely just the gauge.
Very nearly everyone else, who just plug & play, including forum members AND lots of users I meet at public chargers, report range similar to my own 100 miles in 75% city/25% highway.
