DF -
I'm certainly glad YOU weren't injured too.
I have an old 5-10 scale that 'sometimes' the tenth's balance has jumped 1 or 2 notches- no big deal.
I also have a 10-10 scale that is a 'pain' to adjust up/down with the rotor....
BUT so far I've never seen either one jump in 10 gr. increments and I'm GLAD.
Several years ago I moved to digital scales and actually just replaced the first one last Winter. I still use a balance beam for checking wts. but much prefer the digital.
Continued Good Luck.
