I wouldn't be surprised by a ~10% loss in range, which could be enough to make the EPA numbers look bogus to some drivers.
Presumably there's also a subjective element, like if the driver tends to tailgate and brake late, which isn't exactly uncommon. You're not recovering any energy put into heating the brake rotors.
There are also plenty of locales where you're repeatedly braking heavily for hairpin turns like winding roads on the side of a mountain. Teslas aren't exactly light vehicles...
