Probably a stupid question, but you see the Forward Pressure Indicator on the reactor 12's. When they say "with boot inserted and heel closed, the fpi must be within .5mm-2.5mm of sticking out" in the wonderful 'user manual', does this mean that the little black plastic bit (is that even the fpi??!) has to sit out .5-2.5mm further than the similar silver metal bit below it? Cus it don't and the diagram it gives is crap!
