I've "been around a while", raised as a JW in a previous century
There were dozens of JW kids in my congregation and neighboring congregations, within a few years of my age, attending school around the same time.
With just a few exceptions, most of the "good kids" left "the truth" within a few years of graduating high school, while a higher percentage of the "double-lifers" ended up sticking around, some even progressing up the chain of "organizational privileges".
Indeed, hypocrisy abounds within the JW congregations. Hypocrisy is not really objectively measurable, but if it were, I suspect the ratio of it within the JW Org would exceed that of the general population.
