Throttling: Is there a way to get recovery rate of request "bucket" per resource?

[wolendranh]

Hi!

In old Amazon MWS API there is separate DG_Throttling article explaining how throttling works. There are also terms like Restore rate which indicate rate at which your request quota increases over time, up to the maximum request quota (which is currently called burst). Having those values developer could code some mechanism on how to deal with throttling.

How does it work in current SP API? Only values that we have are req/sec and burst. When burst is recovered?
