I consider the range test as simply a means of catching a BMS reset, as LeafSpy alone can't protect against that.
I think it would be highly unlikely that an unscrupulous dealership would take the risk of doing a BMS reset on a car with 85% SOH or better, as most buyers would see 12 capacity bars on a car like that and would assume the battery was in good shape anyways...
By doing a range test on a 2 or 3 bar loser that had a BMS reset, it would be pretty obvious that the battery was lousy.
In other words, the range test doesn't have to be super accurate - its usefulness is in avoiding a Leaf that has great, but fake, LeafSpy stats due to a BMS reset.
