Summary:

Plan Rate Limit configured is not working as expected

Content (required):

Hi experts,

I have an API, 2 Plans associated to the same API and 2 Applications, each Application subscribed to one Plan.

One of the plan has a 10 requests per minute rate plan limit. And the other plan has a 5 requests per minute rate plan limit.

When I consume the API with one of the Applications that is subscribed to the 10 request limit Plan. I never get to execute more than 8 times that API.

And with the other Application that is subscribed to the 5 requests limit Plan, I always get to execute it 4 times before I get the rejection message that the limit has been reached.
