Considering the mileage and unknown condition, I think you're over reacting.
It's stable and doesn't appear to cause issues. Maybe a bit of fine tune might help but if it's working, accelerates, I wouldn't mess with it.
It's a stroked low compression engine, so may not match the "published" levels of more modern ones and wear is a factor. ie, close enough if no issues.

UR using a compound gauge so zeroing is crucial to accuracy. I'd check with a different gauge, if suspect.
