The take away seems to be that the low cost VNA's produce decent results except for when testing non-linear devices (i.e. preamps) where the non-sinusoidal drive signal causes distortion in the device under test. Joe didn't reduce the drive level of the LiteVNA/V2+4 which may have helped with the measurement results.

Delay is calculated by the VNA from the change in S21 phase divided by the change in frequency. Delay variation or dispersion causes higher frequency elements of a digital bitstream to arrive at a different time from lower frequency elements. This stretches out the total bit time and may result in it intruding into the time frame of the next bit.
