hskrntx,
As one who varies from a "down" PAP (the track is called "inverted'), to a "0" or neutral PAP, your drillings will be slightly different, in some cases. 99.99% of the people will see nothing different; only you should know how they are different.
JK300P,
Your PAP is not abnormal, just not average or run of the mill. On eof the finest coaches ever and one of THE most knowledgeable bowling experts alive on the planet, Tom Kouros once said that a crankers best AND Safest tracks was inverted, that is, with the up/down measurement of the PAP being negative.
Just use the degree drillings, NOT The clock drillings. The degree ones are accurate.
