That document you linked is research on archery as used in warfare, not archery tournaments. It does not cover any kind of tournament. (Though I admit I didn't read every single page.)
And yes, we all know that nobles used archery in hunting. No one denies they did.
Please find a historical example of an archery tournament for nobles. Something where, say, the Duke of York picked up a longbow and competed in an archery tournament. I don't know of any, but then again I've never done any kind of extensive search, either. If you can find one, then that adds some substantial weight to your request.
From my source, describing the training of the Knights Hospitaller
"From later Statues and
regulations we learn that the military brethren had to attend not less
than three afternoons a week for gymnastics, wrestling, drill, exercises15
in arms, and shooting with the crossbow and
there was a prize for
marksmanship every two months"It may not have been a part of a tournament but they clearly held archery competitions.
