    I don't know what happened to your posting but here is the answer to your question:



    The gauge is dropped slightly to verify that the tank service valve is not leaking.  If it was the pressure would rise on the gauge.  There is no set amount or other reason to drop the pressure. 



    I double checked to make sure this is still correct with Joe Rose the President of PGANE and he confirmed nothing has changed.

    sorry tim

    I some how erased this post in mistake of another..not really sure how I did that. Thank you for looking into this. The instructor was speaking on behalf of one regulator manufacturer and I was not able to ask him any more specific questions as to why. It made no sense to me in his explanation and makes it harder to verify small drops do to the guage not being that small of a scale....I'll have to see if I cant get in touch with him again..thanks for your help..:)
