What do you mean? I have lots of empirical data. I've run a water pump and a fridge off a GFCI.
I do regularly put in GFCIs for window air conditioners.
I have never have a problem. To me that is a lot of empirical evidence.
However, there is this old wives tale about nuisance tripping. Not a single person has come forward with an actual example. People just believe that it happens. I suggest that it happens only with leaky devices.
