It strikes me that this should be true for the *perfect* clarinet since
pulling the barrel out affects the notes using a shorter tube more than
those using a longer tube. The percentage change in tube length is greater
for the shorter tube. So on an ideal instrument if the B natural using the
shortest possible tube is at the same pitch as the one using the entire
tube then the instrument is in tune with itself.

On a *real* clarinet I don't see how this could work.

What does the "right amount" mean anyway? You can define it any way you
want. If the instrument is designed to play at A440 then you could say that
it means that if you fill in Steve Fowler's tuning chart you'll have as
many notes above the line as below or maybe
averageCentsAbove @-----.
Or maybe you want a procedure to find the ideal pitch of your instrument.
In that case a suppose you want to minimise the spread. In any case what
use is it unless you're playing unaccompanied? Then tuning isn't exactly
critical.

I have seen the advice
somewhere that if the side key middle line B *natural*
and the "normal" overblown version are in tune, then you have the barrel
pulled out the right amount (possibly not at all, of course).
This *seems* OK - does anyone else more or less believe this?
