I've read a couple of conflicting explanations of how the +/- analogue
waveform gets converted into a digital signal that the c64 or c16 can
read, but I'm not sure that is particularly important to the answer.

It's probably that if you keep the ratio the same then you only need to
write one timing routine when saving.

The analogue side might also get upset if you have extreme ratios, as
there is a low pass filter in there.
