Neither of the owners new about the advantages of alternating stalls for the best performance.
It's not just "alternating" -- you have to actually look at the stall numbers.
Older SC installs are:
1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B where "alternating" should work.
But in many more recent SC installs, Tesla has set them up to be:
1A, 2A, 3A, 4A, 1B, 2B, 3B, 4B
And some are even different from that, like Hamilton Marketplace where the paired stalls are back-to-back, so you don't want to "alternate" at all.
If you "alternate" on the newer style SC installs, you'll end up pairing like this, which is really bad:
1A, 2A,
3A, 4A,
1B, 2B,
3B, 4B
or
1A,
2A, 3A,
4A, 1B,
2B, 3B,
4B
So it takes more effort and explanation than "alternating". I've suggested here and to Tesla that since the As and Bs don't really matter (what matters is who gets there first).. that they should just eliminate the As and Bs, and move to a color based system with the paired stalls the same color. So if someone is already on a blue marked stall, move to a stall where both colors are open, and just pick one. That's alot easier than trying to explain the 1A, 2B system to people. At one SC stop, the guy already there was trying to explain the pairing to me, but he got it totally backwards, saying that there are two banks, A and B, so if someone is already on an A stall, use a B stall. Of course that fails if they're both on the same numbered stalls.
I don't remember how the Turkey Lane chargers are set up, I think they're the new interlaced style numbering.
