First of all you have to understand that the PBA patterns were designed for use specifically in a Kegel Sanction machine. They had a hard time converting the patterns over to the new Brunswick machines this year because the technology is so much different. Any time you use a different machine, different oil products and different cleaner products you will receive drastically different results. Another factor is the "double strip". The regional and national tours both double strip the lanes before the patterns are put out. Even in this case the house pattern "memory" still hasn't been completely removed from the lane. This is why you see the patterns play tighter as the tournament goes along. The more times you strip the lane, the more of the house pattern comes off. The more you get the house pattern off, the truer the patter will play.
Of course the PBA patterns will play "easier" than sport patterns. The ratios aren't even close ( except for the US Open, which is harder yet ). In my opinion sport patterns are to extreme. If they had gone to 4 to 1 ratios i think the whole concept would have taken off in a big way, but that another discussion for another day. My point is that all 5 of the PBA patterns play different depending on lane surface and volume of oil. So be careful to the fact that if you have your home bowling center run a PBA pattern for you to practice on, that may be the same numbers going into the machine, but it may not play like what we bowl on. Also keep in mind that if you don't practice with at least 4 people the pair wont break down like it should. In order to get the true PBA pattern experience you need to :
1. Use a Kegel sanction standard machine ( similar to the machine the regions use )
2. Use Brunswick Absolute Oil products
3. Double strip ( if not more ) at least 2 pairs of lanes
4. Be bowling on a good lane surface ( Pro-Anvilane or AMF HPL )
5. Have at least 4 bowlers bowling on the pair
6. Shoot spares because the polyester spare balls make a difference in transitions
That should get you as close as possible to get you ready to bowl a regional. Now i realize its not easy to accomplish all of this so i don't even recommend it. What i do recommend is to invest your time and money in finding a good coach that can help you develop a versatile physical game and develop a good knowledge of lane conditions and equipment. Then whatever pattern is thrown at you will seem easier
