CD labels polarity

So far in my opinion, my random testing of various CD labels has yielded 111 made in polarity and 20 made in inverted polarity. I'll eventually publish a more comprehensive list of the labels. But a few of the labels seem to have both polarities especially the major ones such as CBS, e.g. Bob Dylan CDs. That works out to approximately 15% of CD labels being inverted. My list of label polarities doesn't agree with actual polarity and many of the relative polarities of the labels of the list by Lars Fredell published on page 20 of the Summer 2000 issue Volume 4 No. 2 of UltimateAudio. I wish he was still alive for lots of reasons and I'm sure we'd have very lively and enlightening discussions about polarity. One thing for sure it's not 50-50 as some would have you believe. With over 5,000 CDs I'm sure that I'll eventually be able to publish a fairly comprehensive list of label polarities. And except for test CDs, I have yet to find a commercial CD that doesn't have all tracks in the same relative polarity, i.e. all in polarity or all inverted polarity.
