Why 66/132kHz?

Anyone know the reason why those frequencies were chosen?
I understand that 132kHz is just below the 150khz conducted limit but why 66kHz.
Would maybe 75kHz be a better tradeoff between efficiency and size?
Or perhaps 45khz so both the fundamental and 3rd harmonic are below 150kHz?
Just curious.
