I think we should do #1. Dividing by nloops is never what I personally
want for any of these, but we got enough consensus on it to move
forward with it for the actual row counts, so I think doing the same
thing here makes sense to me. Maybe eventually we will get consensus
on other changes, but I think we probably don't have it now, and doing
what we can do is better than arguing a case we probably won't win.
