The Geotab database right now is the best objective study we have - not perfect by any means, but considering the sample size (6,300 cars) it’s tough to argue against it.
We have the possibility of creating our own Leaf database using data contributed from LeafSpy users. I don’t know how many users there are, but I would guess enough to set up a very credible, objective degradation database. If you could get location, model year, type and SOH on a monthly/quarterly basis you’d have something of real value to Leaf users.
Actually there is something wrong with Leftie's anecdotal 30 kwh observations. They are contradicted by both the updated New Zealand study and the Geotab study. Yes, a database could be created using data from Leaf owners on this site and that would certainly be useful. However, the first thing you would need to do is what Leftie has not. That is to utilize information from vehicles which have undergone the BMS software update - not a mix of pre and post update vehicle information.
