I'd say, Hz is quite regular choice for _this_ ... it's just not referred to as "Hertz" by IT practitioners (usually). Technically Bq and Hz are same unit 1/sec - difference is that Bq is used for random physical events (comparable to web requests) and Hz is used for periodic physical events.

What if we made music from the RPS metrics. I might just do that. .

I use hz to measure my adult fun time. In addition the metric sub unit prefixes, I can make it sound very high to the untrained eye.
