90 second shot clock with 7 timeouts
(If Competitor's agree to shorter shot-clock, not an issue)
I would highly recommend that you set up 90 seconds for all, no other option. Thus avoiding conflicts or disputes during the tourney. All the participants on the same level.
Shot or Putting Concede's
(Distances of concession's are squarely between Competitors as well as to use it or not)
Again here, NO Conceding putts. Everyone has to putt to the end, has any tourneys or ranked stroke games. And avoiding unfairness and unwanted conflicts.
my 2 cents
p.s. Great Simple Rules beside those 2 issues.
