7. Is this level of accuracy related to the difference of the (diagnostic measured) clock speed from 4MHz? (which is always a bit less than 4MHz).

Actually, the nominal CPU clock speed for the Yorke-based Saturn CPU is 3932160Hz . But, as we all know, for some reason this can vary and be as low as 3.68MHz ( Although, I have only seen slower frequencies around 3.69MHz in the wild ).
