I've solved the problem, which has to do with the generating function for 'k'.$k$.

For example:

• $k = -108*t^2 + 36*t - 67 67$ always has even parity
• $k = -108*t^2 + 36*t - 7 7$ always has odd parity
• $k = -108*t^2 + 36*t - 84 84$ is 50/50 $50/50$ odd and even

These, and other similar functions, generate nice groupings in residue classes modulo 504 and explain the population distribution of odd and even ranks in those residue classes.
