Backcast? You drill your belly holes and stuff before you turn your plug???

I never heard of anyone doing it that way....how accurate are your depths when you are finished?
I turn my plug first....leave the square ends on and then go ahead and drill my eyes, belly swivel holes, and weight holes and such.....then trim the ends off with a small saw....comes out awesome! I thru-drill the block on my drill press before I turn and use the holes for center....works great!
