 In the above example, frontend1 is configured to limit requests by the client's ip address.  
-An average of 100 requests every 10 seconds is allowed and an average of 5 requests every 3 seconds.  
-These can "burst" up to 200 and 10 in each period respectively. 
+A sustained rate of 100 requests every 10 seconds (10 req/s) is allowed for rateset1, and 5 requests every 3 seconds (~1.67 req/s) for rateset2.  
+In addition, these can "burst" up to 200 and 10 in each period respectively.
+
+Another way to describe the above parameters, is to use the [leaky bucket](https://en.wikipedia.org/wiki/Leaky_bucket) analogy:
+for rateset1, the size of the bucket is 200 drops, and it is leaking at a rate of 10 drop/s.
+If the incoming rate of drops falling into the bucket gets high enough that the bucket gets filled,
+any subsequent drop overflows out of the bucket (i.e. the request is discarded).
+This situation holds until the incoming rate gets low enough again, and remains that way, for the water level in the bucket to go down.
