When a puppet request is put in, a message is generated by the system informing you of the average wait time for requests this week (rolling week, not calendar week).
Likewise, once a puppet request is put in, after is has been in the system for say an hour or so, it's time is then tracked to modify the wait timer once it is responded to.
Just a simple 'The average wait time for puppet requests this week is 2 days' would be a nice thing to see, so you can sort of plan on proceeding with your RP plans around knowing that your request is likely going to be answered in that many days.
