Sorry TonyPhil , you appear to be under the misapprehension that WD means people have actually WithDrawn.
I made a post to this effect a few days ago - I have a small window each day when I get time to play a proper game ( i.e. 9 holes not CCTH or anything like that) - however this regularly coincides with that ridiculous "Be Right Back" message - as a result if there is only a few hours of the Bracket to go , then, quite simply I am not allowed to complete my round. Rather than blaming the players I suggest you consider the fact that brackets, in their present form ARE a bit of a joke. For people with busy schedule they are not worth it. I will not be taking part ANY paid bracket tournament until the countdown timer is resolved.
A simple resolution would be to keep the countdown, but to let me play all 4 rounds in advance - just releasing each score to public view when the timer has countdown/or until everyone has completed that appropriate round. Its really not that complicated. It may also speed up the tournament.
Often, those extra 2/3 rounds which I did would be of no use - that would be fine with me - its all good practice after all. Also, at least then you would find out who has really actually WithDrawn / couldn't be bothered.
