A couple of users recently seemed to have gained range and improved battery performance after either an L1 slow charge to 100% , a lengthy road trip, or both.

So yesterday I pulled the 240V at 75% and let the car charge to 100% overnight on the 120V charge cable thinking that may give the car some cell balancing opportunity. I have no data to back it up, but it sure seems to have worked as I achieved my highest-ever capacity remaining estimate yesterday aside from the tightly-controlled Tony Williams test...

On our way back, the deterioration values changed. It was "7EC 24 00 32 2B 00 06 0D" before, I have now "7EC 24 00 2D 2D 00 01 01".
Perhaps this is consistent with a recommendation on the Battery University site to do a battery calibration once every 3 months.
