It was not talking about the rate limit but the performance of the applications. Performances must never be accounted in request/min. It's only requests/s that matter, because your performances are defined by the peak load you can take (which is many times the minute average). Limits should be on more than a few seconds to support short peaks, yet throttle quickly if they persist.
