The part that ISN'T easy for me is the whole thing where somehow a charger elsewhere in the row is ALSO to be avoided. I dunno how to put that formula into words (and didn't see a clear explanation when I revisited the page courtesy of your tip). Maybe I should just print out that checkerboard and carry a copy in the car.[/USER]
I'm not 100% sure what you're referring to by the stall elsewhere in the row should also be avoided, but here is my guess.. see if this helps:
You have it correct - 1A and 1B share, 2A and 2B share, etc. This is how 99% of the SCs work. There may still be a few very old locations that don't use this standard. What I think you're getting at is that 1A and 1B MAY not be physically next to each other. This is true. The PHYSICAL placement of the stalls varies by location, and it's dictated by the lease agreement and the nature of the parking. If all slots are Tesla EV charging only, then it goes 1A, 1B, 2A, 2B, 3A, 3B ... If half the spots are Tesla EV charging only, and the other half are general parking, then the stalls are usually placed "1A 2A 3A 4A 1B 2B 3B". This way each dedicated charging spot shares an SC cabinet with a general parking spot which may be ICEd. What Tesla is trying to avoid is two cars sharing a charging cabinet while another sits idle because of non-Teslas in the general parking.
Make sense? Just follow the labeling on the pedestals and you'll be good every time.
