No: Far better than 3.1 bits.

Duty cycle is expressed as N/M, where _both_ N and M are variable, tho' M is
constrained on the high end by a minimum frequency requirement.

You can get a lot of closely spaced values when you can vary both numerator
and denominator, tho'  I imagine there might be some small holes in the
spacing.

Q: Given N and M with N > 0, N < M, M <= maxcount, what is the largest space
between realizable duty cycles?

This is really a _great_ scheme!
