Their amps reported on the dash .vs. actual amps delivered, (trust me, I measure at more than one place when charging) can be goofy at times. Not sure if they are measuring amps into the battery or into the charger at times. When I am charging 115 vac, about 1600 watts To the bike is about the max it will flow, when running at 240, i get about 3400 watts TO the bike. Now that this came up from someone else, next time I charge im going to push my inverter to about 250 ish volts, see if it boosts reported watts, ill also buck it back down to around 230 volts too, and see how that affects it's reported amps / volts / KW charging. I get an idea though, that it's not super dooper accurate really, and on average, I seem to be getting 5.6 miles per KW delivered OUT of the receptacle, heading to the bike. that 5.6 is out the door, including all the conversion losses, heat losses ble bla bla.
