Don't forget, tube persistence has much to do with visibility of "flicker".
I have an analog storage scope at home that can save a single-shot trace
for several minutes before you can see a change in the scan.

56Hz won't
produce any flicker a human can detect. It may beat with the
local
lighting, but it won't flicker noticeably.
I can *easily* see 56 & 60Hz flicker, and anything below 72Hz can give me a
headache. (Interlaced VGA can give me a *monster* headache in under 30
minutes.) 75Hz for me is borderline but usable, and 85Hz & above are my
"target zones".
(also, the larger the tube, the easier it is to see the flicker -- at least
for me - I'm running 75Hz at work on a 19" tube, and I can still see it.)
Just because *you* cannot see the flicker, doesn't mean all humans cannot
see or be affected by the flicker.
