The Kegel patterns are simple a set of patterns of different lengths and oil ratios that Kegel has developed.
They actually come in 3 levels of difficulty - a Recreation series, which have much more oil in the center than the outsides (like a typical house shot), the Challenge series, which are flatter but not quite sport compliant, and the Sport series, which are USBC sport compliant. The 4 patterns in each series are all different lengths - 3 of the 4 Recreation series ones would play similar to a THS, the 4th would play a bit tighter due to its length. The Sport series of patterns should play just as hard as the PBA shots. The Challenge series would lay somewhere in between.
To answer which shot was actually laid down, PBA Regional tournaments use the PBA animal patterns. You can actually see which pattern is used for each tournament on the website.
I don't see a regional tournament that recently occured in your area though... http://www.pba.com/regional/region.asp?ID=2
If by "regional" you just mean a large tournament in your area, then the center/tournament director can put down whatever they like. Your best bet to find out what you're bowling on during league is to ask the lane man. Second would be to ask a manager, and third a desk person - the desk people usually don't know though.
