Would you believe... the record is pressed off center!
Side 1, with the sine waves at precise frequencies, including one band at 3150 Hz to check wow and flutter, is off enough that the arm visibly moves side to side, and the readings vary regularly to match.
FWIW the OM30 on the JVC QL Y66F produces nice sine waves.

I have a plan to correct the situation. Place the record on the Micro Seiki's platter and watch carefully when the eccentric comes around. Then, give the spindle a hefty whack with a ball pein hammer in the opposite direction to the off centre direction.
If you were close by, I would have been glad to help you out by setting up a finger clock on a magnetic stand with the clock's finger touching the record edge, showing the exact amount of deflection from true centre. Then, I have another tool which determines whacking force. All old hat and a piece of cake if ya know what I mean.
Glad to have come to your assistance to sort this minor little problem.
