it happened to many, even the pros, just look at the recent SG
open, what happen to those after a perfect game?
Bcoz during the high game, so much focus was packed in that game,
when it all restart with a new game, to carry forward the same
momentum is not that easy even the mind wanted to.
Its a mind & body game, it inevitable, but to be consistence,
mental game must be trained, so do the physical game.
Exposure to more competitive games will get you there sooner.
Happy Bowling
