The way your posts are worded indicate to me that you are against having your piano's tested, if not then why your initial question, just get it done and accept the bonuses.

You've worked yourself up into such a state that you've forgotten who posed the original question.
Magnificent.
I do a lot of work in the public entertainment field and I'm often required to interface with other peoples kit. Due to the condition to some of it I refuse point blank. Accordingly some peoples total disregard for safety [including PAT] has beome one of my pet hates.
I haven't really worked myself into a state, more a question of lost faith.
I still stand by the quote you have used but to clarify my intent, it was aimed at the OP GRC.
Again I apologise for confusing the 2 posters.
