I don’t know about the test it 50 times thing but in general if one is going to recommend a poorly understood solution of any sort, especially a pricier solution, doing diligence to verify findings can only help. Making a change and saying you hear a (positive) difference of some sort is something......but not much, especially when that is all there is for people to go on.
It’s ok to do it once and say what you hear, but not Ok to jump to the conclusion that you are infallible and others will surely hear the same thing. Even worse then is to discount others when they report something different even if based on similar low level of diligence.
