I bowled a 4 game tournament on this same 46ft pattern. With 6 regional pros and 20+ 225+avg bowlers, first place was a 206 avg for 4 games.
Bottom line, if you didn't have tour rev rate, or threw 500 grit 13 MPH, your ball was skating on ice for 50 feet with maybe 3-4 boards hook down lane if you're lucky.
They (the pros) know what they're doing and have the revrate and equipment to avg 240 on anything. Us mere mortals can't hit what they're bowling on to anywhere close the clip they get to. Get over it.
I disagree with your assessment. Duke (5th), Pepe (6th) , Walter Ray Williams (13th) Bohn (18th), and Pluhowsky (24th) do not have what anyone would call "tour rev rates". And from the looks of it on XtraFrame, they were not throwing 500 grit bowling balls. Pepe was throwing a Storm Rocket during the early part of match play on Thursday if I remember correctly...and Norm ended up throwing a Hyper Cell Skid (which is not an oiler) on the show...
My theory as to why scores were so high is based on lane topography. I think the underlying friction under the pattern was high enough and in the right spots (mostly on the leftside of the lane given the lefties success in the tournament) that it played easier than a "normally hard" sport shot. In addition, from what I saw, the pin carry was excellent as the side boards were quite lively. I also guess that where you bowled on that pattern, the lane topography was not conducive to high scores and that's why no one could hit it.
Just some guesses...For all we know, maybe someone messed up and programmed a house shot into the machine and didn't tell anyone. Highly unlikely, but who knows! We're all just guessing....
