I suppose if you were to test each pin with a torque wrench there would be a few pounds difference between pins but who cares. Maybe a torque difference was from mis-sized pins. That's why I mic the pins, placing the smaller diameter pins up top with the larger pins in the bass and discard the oval pins [a spring loaded dial thickness gage (micrometer) helps in this regard] I have mic'd as many as four different sizes within a set. .280, .281, .282, .283; sometimes even .279 and .284. Mic'ing smooths out the feel of the pins, understandably. I even run the brush through a new block after drilling to remove any glazing left by the bit. But it definitely helps after the pins burnished the holes during removal, I also dip the pin into powdered rosin before driving.
