aqPerformance questions

I have recently discovered the aqPerformance counter. I have questions:

I was running version 10.60 and never saw this feature before.  I recently installed TC11 and added the WEB module.

a) Is this new with version 11?

b) Is there a way to reset the counter without generating a warning message?

c) I had to read the online documentation in order to confirm that the ".start" method resets the counter if called on an already started counter.

Thanks
