Maybe he means fixed vs. automatic gain (or threshold)? Perhaps a worry about
picking up higher frequency noise on a lower frequency but larger signal you are
looking to measure?

This high sensitivity is probably a bad thing, not a good thing. It is
indicative of a dynamic divider. For a frequency counter prescaler, you
want a static divider, such as the HP5386 used. Dynamic dividers make
errors
if the signal being measured has a broadband noise floor or sufficiently
high spurs at any frequency.
What do static and dynamic mean in that context? Is it the same as DRAM
vs
SRAM? If so, I don't see any obvious way that translates into one works
and
the other doesn't.
I wondered that.....

The MB510 looks to be a series of flip-flops so presumably would be
classified as a static divider?
