The success rate only counts requests that have left the originating 
node's search queue - if the throttle is working, searches shouldn't be 
released from the queue more quickly than the network can handle them, 
so the success rate should level out.

This is also the reason the success rate for 'backoff only' continues to 
drop when 'throttle and backoff' and 'throttle only' have levelled out - 
backoff on its own doesn't prevent searches from starting.
