Good to hear it worked.
That 4% is probably from that one cell :/. We've lost just under 6% in 12 months, despite doing everything we can to look after the battery. But that's 30,000km of driving (40-70k km) and still 11 SOH Bars left.
The screen in LeafSpy showing the individual cells (blue/red bar graph) is the one that'll be of most interest to you.

3. Pair dongle with phone 4. Open Leafspy and select Bluetooth 4.X LE dongle ( not BT paired devices). Um, my understanding is that LE dongles don't pair. You point out in step 4 that it's not a paired device. So, I would think that you should skip step 3. I actually wasted a fair bit of time trying to get my phone to pair with my LE, and could not. So I hope to spare other readers that hassle. The Samsung paired with the LELink (as in, it noted the device and we paired both). We also selected Bluetooth 4.X LE dongle. Was probably less than 60 seconds to do both. The case might be that either works or both, and trial and error is necessary. Bottom line is that even after various trial and error rounds OBD 2 Australia didn't work with the Leaf, but LE Link did. The LeafSpy programmer gives useful info in the help menu of LeafSpy as well.
Would probably be helpful for all of us noobs to know how to interpret the LeafSpy data beyond SOC and SOH, especially given that one blue bar from the battery read out

Thanks tomkauf, sounds as though you have still gotten a good amount of kms from that one lost bar. We will keep everyone updated after the trip to Nissan to see what they make of the possibility to "talk" to the Leaf's japanese software.
Will upload a pic of the blue/red bar graph for group analysis later.

I actually wasted a fair bit of time trying to get my phone to pair with my LE, and could not... The Samsung paired with the LELink (as in, it noted the device and we paired both). Ah! I must be confusing pairing with connecting, my bad. I guess the phone needs to pair with the dongle, to say to the phone "this thing is something I want you to connect to some of the time, it's not something belonging to the neighbours that you should ignore". Perhaps the dongle does something similar, as in "this is my phone, I will be connecting to it; don't ignore it like I expect you to ignore the phone of passers by". This is a once-off thing. Then with a normal dongle, you have to "connect" to it every session. That's the step you don't have to do when you have an LE type dongle. You just tell LeafSpy that you use an LE type dongle (and it remembers that), so after the first time, there is no delay connecting to the dongle. Thanks for straightening out my thoughts

tomkauf and anyone else interested: the Nissan dealer was super helpful but after the Nissan state rep telling us we could ask this dealer to troubleshoot the battery, when the dealer confirmed that in writing with the Nissan state rep, the dealer was told to upgrade his certification! So that was a wasted trip to town. In short, will be another couple of months before the weak cell module can be replaced (but we did confirm that so far the Nissan dealer computers will talk to our Jap import Leaf). LeafSpy showed weak cell #47 at low charge, so we turtled to the rapid charge station (that was a bit of an adventure!) and the 204mV readings at the low charge are now back at 25mV reading with a 50% charge. The rapid charge also filled the battery 210km at 93% charge (rapid charger would not go beyond that) - but the 52km trip home took 105km of charge (300m vert gain and 110kmph for 30km probably account for most of that) so the battery range isn't great, even though the SOH is still showing 83.4% and all 12 bars.

Hi coulombyep you hit the nail on the head. The LELink and the phone auto talk without having to tell either to do that, ie turn on Leaf, put in dongle, activate LeafSpy on phone and phone/LeafSpy pick up all the data from the dongle. Pretty amazing really.
