Let me alter what you said to make a more accurate statement according to
my understanding:

"The maximum theoretical HF frequency on replay is defined by the ratio of
the replay speed / head gap size. This is because the highest resolvable
wavelength will be limited by the gap size,

lowest resolvable wavelength
