YES!!, more analogous space should be filled

i agree that the needle always travels at the same velocity, the record is
always turning at 33-1/3 rpms.
but the circumference of

on the outside, the record has a larger diameter. played at 33-1/3 rpms,
you
could play a locked groove with less bpm. on the inside, it is smaller and
you could play more bpm. i mean, the difference in circumference is like 19
inches! (2pi5 - 2pi2). maybe i'm just wrong.
a common misconception

not philosphy - mechanics!
33 rpm actually means 33-1/3 rpms.
so, to get a one beat measure into a locked groove, it has to be 33-1/3
beats per minute.
if we want four beats, they have to go four times as fast to fit into the
l
listen to any lock groove track and you'll
notice, if the pitch is at 0, that the bpm of
the lock groove is always 133.
that's because a lock groove is one revolution
(around the record once in a groove whose
start meets its end). something to do with
33 revolutions per minute. i'm no math
