Okay, I ran all of this by Mom, and she said her 401A has never skipped stitches. The school's Slant machines (404, 401, 403, 501, 503) didn't, either. (Only the Touch & Swears did that, and she evicted all of them and replaced them with Japanese Kenmores, lol.)
The only thing she could think of that has not already been covered in this particular Slant discussion is needle either a smidge too high or too low and did you try setting it higher or lower in the needle clamp.
eta: I was NOT laughing at you, AA/Tammi. I was just amused by the solution, that apparently one prima dona needs to do things "by the book."
