No, I don't have a spreadsheet on that one.
The rationale for keeping the arm/cartridge resonance frequency above 8-Hz is based on warp frequencies estimated to be in the neighborhood of 4-Hz and below if I remember correctly. Maybe it was 6-Hz and below.
Anyway, Bry is correct about the revolution frequency being 0.555-Hz. This would be the frequency of an off-center spindle hole. An elliptical groove would produce a frequency of 1.11-Hz. Warps can be anywhere at or above those frequencies, but probably rarely higher than 6-Hz.
Best regards,
