Yes exactly. I must have 10 test records including the ones used by National broadcasting Companies, not a single on has correctly centered hole , or without 1-revolution-error, and are quite useless for speed variability tests, and possibly other test only have relative value. Vinyl is is just too technically flawed to bring me any pleasure. I cannot listen to any vinyl system without being annoyed the speed variations (0.1% variations are ver noticeable to me)If case you haven't already noticed, the test records used are eccentric. The yellow line is the wow and flutter of the test disc, the green line is the result once the wow & flutter is taken out of the result:

In order to determine wow & flutter and speed accuracy, one has to calculate around the wow built into the test discs. No LP has the speed accuracy of digital sources. Full stop. As I have posted repeatedly, the real issue is not the playback gear, which can evolve, but the discs themselves, which cannot.
I keep my system just for sentimental reasons
