It's tempting to think that it could be somewhere near the

They're the same thing.

By balance arm, I meant the distance between CG and CP. Missing
something, am I?

Well, that'd be a misdefinition. Also, CP really should read CL

But we need some term for what I referred to as the balance arm, i.e.
the distance between CG and CL (CP).

No we don't, you just defined it.

Bertie

Are you saying that CG and CL are the same? I definitely remember
reading that they're different.
