Review Comment:
A different threshold for each command sounds great but also sounds like a
lot of work and way more chances to break something for what feels like
marginal benefit to me. Either way, I'd propose we get the test implemented
then work on improvements and adjust the test thresholds (hopefully
down/tighter) as improvements are implemented, right?
