+A client implementing a simple ratio between remaining keyword and reset keyword could infer an average throughput of 1000 quota units per second, while the limit keyword conveys a quota-policy with an average of 10 quota units per second.
 If the service cannot handle such load, it should return either a lower remaining keyword value or an higher reset keyword value.
 Moreover, complementing large time window quota policies with a short time window one mitigates those risks.
