Because 11 is louder. It is one more than 10! Duh!

Why don’t I just make 10 a little louder and then make 10 the top
number and make that a little louder?

I’m going to say the obvious thing here: Surely it should show the
volume as 0-11?

Thanks; good advice. I am an EE with 12 years of experience and
have worked with HV before. Built my own tube amp with 420 VDC
inside. Would love to hear your tips.
What I'm actually building is a volume display for a tube amp.
When you turn the volume pot, a couple of nixies will display
0-99. The amp in question already has a transformer that delivers
220VAC, so I will be dropping and rectifying that to get my 180V
for the nixie anodes.

I dont recommend line-operated designs unless you've done
some previous design work at high-ish voltages. There are a
lot of not-obvious things that go wrong (line noise,
transients, component failure, inadequate isolation) with
very bad consequences.
If you have done a lot of past designs, I can share some tips
on how to make a line-operated design safer and more
reliable. The last thing we want is for someone's nixie clock
to cause a fire, or worse.
I've had a few "learning experiences" with line-operated
circuits that ended-up with sparks, smoke, and/or small
explosions despite careful forethought. There's always
something you overlook, and sooner or later it will get you.
