There is none for vfr traffic - but supposedly vfr traffic should be flying
on the 500 ft intervals.

Where can you read about the +/- 100 feet, I couldn't find it in the
far-aim.

Why do you say "a little steep?" Clearly if you understand what is
going on
there would not be a question. (assuming US/FAA)

vfr traffic 500 feet above/below
altimeter error allowed - 75 feet.
deviation of 100 feet
deviation of VFR traffic - 100 ft

Add up those errors and you have only 150 ft of separation
