With all due respect I play a lot of tournaments big and small and MOST people in the events (especially the am's) don't know most of the rules...So in that situation you are wrong.
Secondly my issue isn't about knowing the rule, it's about how it is implemented. The PDGA posts the picture with all of the discs in the basket and then says these are in and these are out...and then it comes to the weggie disc and says this one is out, except if no one sees it then we give the benefit of the doubt to the player... That last part is where I have my problem.
Almost every event I have played there are many times where someone in my group doesn't play by the rules and states "come on we are just doing this for fun" or I happen to be leading and then all of a sudden my out of bounds locations seem to be less and less in my favor. This is the problem in competitive sports when you leave things up to judgement calls and players favor and the people they are competing against.
Lastly I do have a problem with the wording.
"come to rest supported by the chains and/or the inner cylinder (bottom AND inside wall) of the tray"
If you want to read the rule exactly as it is written it does say both the bottom and the inside wall, so any disc just sitting on the bottom would not be considered holed out...if you read the rule as it is written. I would never suggest that to be the case, but that is how it is written
