Letters on Class B altitude indications on charts

So what? They are regions of airspace under the Bravo where I can go
without runing into heavies and without talking to anybody as long as
I stay under the Bravo and above the Deltas for San Carlos, Palo Alto,
Moffett, Hayward, and Livermore.

Yes, but these letters clearly refer to the Class B airspace, not
areas outside that airspace.

(And above San Jose's Charlie. Oakland's Charlie extends upward all
the way to the bottom of the SFO Bravo, but it has a 1500-foot floor
over the Potrero and SOMA neighborhoods of SF and across the Bay
Bridge to downtown Oakland.)

Yes, the chart agrees with you, although I'm not sure I see the
relevance of this.

Why so many notches in the airspace under the Bravo? Because there
are three major jetports inside the SFO mode-C veil, one
quasi-government field where the POTUS and Veep fly into when they
come to town, five towered GA fields[1], and two non-towered fields.
In addition, there are 2000-foot mountain ridges down either side of
SF Bay, except some of those mountains get to be 3000 to 4000 feet
high at the south end.

See above.

And I think K is an aerobatic practice area.

I don't see any notation of this on the chart, and the K sector itself
starts at 5000 feet. I presume people are not cleared into Class B
for the purpose of aerobatics.
