I understand, which is why I chose the word "seem." I would also say your point cuts both ways. My observance of the strength displayed by these individuals cannot be definitively attributed to box squatting. But I can definitively say that these individuals have achieved significant levels of strength in the absence of squatting as described in SS which in turn would mean that the SS method of squatting is not necessary for the development of the displayed levels of strength in these particular individuals.
Also....I only LBBS as described in SS. So my interest is more from an interest in gaining knowledge rather than a defense of something I do.
