The 30 second shot time limit was fine for Kiawah and Bethpage(sans #15) and also considering Tournament greens were the fastest back then.
With a green speed of Champ 13 (and higher) and the much more contoured greens of Merion, Pinehurst2, and now Chambers Bay, its time for WGT to raise that shot time limit a bit and give these shots the needed time to complete.
I did submit a Problem Report on the above replay to get the suggestion in their system.
