Actually, received feedback from another forummer that 0.972 was not highest. highest was 0.99 by Mika at 2010 US Open. Below are comments from forummer
"Mika Immonen vs. Jason Klatt at the 2010 U.S. Open 9-Ball
Mika shot a 9.90 TPA and Klatt shot a 9.72 TPA in losing
Mika pocketed 96 balls and Jason 35 balls, no misses
They each had only one position error
Mika won the match 11-4"
So if Berg or Kevin had only 1 error , they may equal Mika's record
