Just a thought ---it really seems the bogey glitch is actually a worthy penalty if someone in the showdown quits or forfeits, but you are not always playing people in showdowns...
it seems WGT should create a showdown ONLY coin room. - cost of entry does not matter, who you play does not matter. ALL that matters is your score and whether you complete your rounds.
you have experts playing tour pros in the Expert division against players who clearly are not playing in the Expert division but merely have silver coins to throw away... same thing can happen in the Veteran division - where even more lower tier players are willing to throw away 10k coins and not complete the game.
Ultimately it does not matter if you win or lose your coins but your score... so why not just make a showdown ONLY coin room - where entrance is contingent on being in the showdown.
Afterall, once the showdown begins, no one not entered can get in and look at leaderboards. So WGT is already screening out players in that regard.
