I have managed to fix the vertical problem,
Yes--I was using the Y-extent of the number plus the line, so when the line extends below the number, both get pushed up. > but the horizontal problem has me flummoxed. I'm shifting the stencil to the centered position by altering its X-extent. Looks like I made an error in calculation. I've inserted the correction in your revised function in the attached file.

As far as I can tell, this function produces fingering numbers in a similar way to how they are ordinarily produced, judging by the default settings for Fingering properties 'text and 'stencil (ly:fingering::calc-text found in scm/output-lib.scm and ly:text-interface::print in lily/text-interface.cc, respectively). Hope this helps, David
