It could be as simple one of these:
1. The design goal was 85 kWh. All the marketing folks ran with that. As the detailed design work was done, capacity wound up dropping to the aforesaid ~81 kWh. Should they have 'fessed up? Probably. But it's not like that scenario has never happened before!
2. Engineer says to marketing guy: "Capacity is 81 kWh." Marketing guy has just enough smarts to know about the ~4k reserve. Without double-checking he assume engineer meant 81 kWh usable capacity, so adds 4 to 81 and comes up with the 85kWh advertised rating. Again, should they have 'fessed up? Probably. But it's not like that scenario has never happened before, either!
I seriously doubt there was anything nefarious going on with the 85 kWh claim. You'll need a smoking gun to convince me otherwise. Meanwhile, I'm not going to fret over it. My soon-to-arrive 90D whether it has 90 or 85 kWh actual capacity, will do just fine.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
