How activemq statistics plugin calculates averageEnqueueTime and other attributes??

I need to find out the average time , a message stays in the queue before it
gets de-queued.

I believe averageEnqueueTime will be the closest attribute that I can use
for the purpose (Please correct me if I am wrong). But the platform I am
using, does not support statistics pluging for now and will be supported in
future.

I want to mock the results , as when the plugin is available there should
not be any difference in the statistics

*PS:* Since time of enqueue and dequeue is logged (DB), I can us these data
to calculate the average time, the message spent in queue, before getting
picked up. 

Thanks in advance
Happy Coding

Why not dig into the code and see how it works, it's all open and easy 
to look at on Github

Note, BTW, that this doesn't include the time the message is unconsumed in
the consumer' s prefetch buffer.

SUM(DispatchTime - EnqueueTime)/COUNT

The computation is done here:
