Well, not quite: Depending on the stiffness of your PLL, you can
minimize phase error at the cost of frequency error or frequency
error at the cost of phase error, and either is a valid engineering
decision depending which of the two are more important to you.

Never attribute to malice what can adequately be explained by incompetence.
