The Petersen is the TRUEST test of real bowling there is, period! The reason is quite simple...bowling is a game where the goal is to knock down as many pins as possible.
That is the REAL goal of bowling, knocking down as many pins as possible. It is not about what line can you play, how much you rev it, how hard you throw it, what ball you throw, or what hand you throw it with.
Also, actually COMPETING at the Petersen takes quite a bit of skill. A plastic ball will just as easily hook off the lane as any other ball, depending on the lane condition...and throwing it hard doesn't mean it won't hook either. To throw is straight on some of those lanes is a skill. Trying to find a way to throw a strike on 60ft of oil with an off-set rack? Sure anyone can get lucky once, but if you shoot over 200 there...that is skill.
In many ways the Petersen reduces bowling to its main, simple goal...knock down 10 pins. Almost all of the other variables that most bowlers gripe about are taken away. Those that "get it" love this tournament. Those that don't, bitch and moan...kind of like bowling in most any other league/tournament.
