i don't disagree with the fact that this system is used on the USPGA, however the only usual reason for it coming into play there is as thunder says where the trny cannot be finished and there are 2 or more people in 1st usually a playoff decides ties.
the case here is slightly differant in that since there is only 1 round, ideally i would love to have a tie break round to decide tied trny but since that might not be viable in the kinds of trnys we are talking about i think that ties should be left as is, as ties. So long as the winning scores are the same there should be no reason why my 65 is better than another persons or his/hers is better than mine.
The USPGAs system is 1 that is used to find a winner in the rare cases that a trny cannot be finihsed, i think that WTG should use a differant system as. all single play trnys are 1 round therefore there is a high probability that there will be a large volume of ties therein some system should be thought up and instituted to handle a trny system that will involve alot of ties or just let them be ties.
