Firstly, nice work to everyone doing well at these events. Somebody will capitalise on what's there and win. Sometimes what's there demands high scores to win.
That said, comparing amateurs (here, Asia or Europe) with the PBA is like saying a scratch golfer can go and play PGA. It just doesn't work that way. PBA players shoot big numbers on the Viper and Shark patterns with major OOB's as well as the wide open spaces.
