Bullshit. Well mostly they will be right. It is a good guess. In the case of LG it had a NPS over 1M. That this high nps was not only "optical" was proven by it's remarkable tactical abilities. I would think: A woodhacker, with hardly any eval. Suddenly it's down to 200k. How come? Well, in this case, my guess would be some eval was stuck into it. What's yours? Ciao, Bas.
