If it was actually that easy, it would already be happening, would it not?
You would have to run tapes of the lanes proving the pattern, and be subject to spot checks and verification. If you are found out of compliance, all honor scores that were bowled for the season are subsequently deemed illegitimate. Basically, you make a punishment for failure to comply a "worth while" reason to stay in compliance. If all of sudden, you have league bowlers loosing their "award-able scores" because the bowling center wants to cheat, well then you will have some very angry bowlers and that would affect the proprietors bottom line. If you affect money, you will see centers staying in compliance.
I don't agree that it would be "impossible" to enforce.
It could be, if the USBC would actually take the time to fix some of the real issues that are affecting bowling, instead of these ridiculous issues like hiding the patterns, and not allowing practice on lanes before bowling.
Fix what the real problems are.
Sorry people, but when 12 year old kids are "out scoring" adults, you can't market that to corporate America as a "good" thing, and show that bowling has integrity, and then sell the product. When you watch someone bowl, you should be able to tell if they are a professional, or an amateur, and their score should reflect that. Today, it's the other way around, your score says if you are good or not, even though people that can score, can't hit the same spot twice in three games.
