On this years bows all I had to do after the initial shoot in period was re synch the cams so they hit the back wall at the same time.
My Patriot was done after 200 shots and the Pro40 was done after 300 shots neither bow was put back into a vise to do any more timing and I shoot a lot
I would say since I got the Patriot back in January it has been shot 20k times and is still in perfect time.
With todays string materials and the way strings are made there is less creep or stretch unlike in 90' s where the strings stretched a lot and you had to continually tinker with the bow to keep them in time.
I was just talking to my wife and she has agreed to let me buy 1 bow[:' (] for next year and the Black Knight is on my very short list
