| I think that is a slight misinterpretation of the truth,scotstoxo. I think somewhere along the line, the Chinese whispers got in.
I believe the truth is that to drill and tap a hole in a bushing, to then fit the bushing into a riser and expect it all to line up on dead centre is almost impossible. Putting the long rod in, accentuates the amount of error in the work.Manufacturers don't deliberately get it off to one side, they just make a reasonably good attempt to be right and if not, they leave it. Sometimes the error is in the longrod so using it as a guide may not be the best way.
Setting centre shot by the long rod is not right or wrong it is a matter of where you start and what you consider to be true centre and dead ahead. Finding true centre or dead ahead is not as easy as it seems, if it was, there would not be so many different ideas about it. Some start by what looks right. Some start by measuring from specific places on the bow. Where you start is not too important in my opinion, so long as it is somewhere close. Where you finish is more important as that will be the set up you use for shooting. Some even say that the tuning does not need to be so close to perfect anyway.
I hope this makes sense and helps you with the puzzle.
All the best
