Have to disagree with the wake descending @ 200fpm statement.
Many moons ago (most likely in the same aircraft Contract Con alluded to) we would regularly fly in company out to an island. I felt the wake of the preceeding aircraft when they were up to two miles ahead.
With both aircraft on autopilot with working alt holds, the front one would throttle back and we would speed up and when arriving in "company" we'd be almost exactly the same height - certainly not the 150 feet or so difference as suggested by that rule.
And for the record, yes a good feeling to hit it on your check rides!
