Congratulations on re-highlighting my greatest complaint about your qualm-making, a propensity for adding factors into the mix that have nothing to do with the big picture.

To me, 47 or 37 req/s seems like a fantastically immaterial difference. It's just not a big enough change in magnitude to really affect the situation.

Accurate qualm, and being technically correct. Personally I'd try to find a more liberal minded approach when trying to hold in my mind the question for what efficient set membership might be good for.

The change in magnitude is over 20%; if you're thinking about it in terms of "change in magnitude", it's huge.

As FridgeSeal points out, both numbers are very small, but that's not a reason you'd want to set up an inaccurate triage system on top of the accurate one. If you don't have very much work to do, you don't need to invest much in optimizing it.
