All the chest beating isn't really necessary. I think everyone here knows there is a real difference but they are just trying to quickly deploy a system.

I am too tired to reply to this but I have taken HAA Level 1 and know what it is like to actually calibrate a system.

If you drop the word calibrate and use setup it may change the discussion a bit.

I have my installers run the AVR's setup for basic purposes.

I don't know how many charge and actually really calibrate a system.

Try educating folks instead of shunning them for their perceived short comings. It really is better for everyone.
