It seems that measuring devices are both a blessing and a curse, as they typically lead to a serious attack of Audiophillia Nervosa. Case in point; the Feickert Platterspeed app available from the iTunes store. When I listen to my analog front end, it sounds excellent and I don't really notice any deficiencies. Of course, I don't have a second point of reference.
Below are the Platterspeed results after dialing in my speed as tightly as I can. The question at hand. . .is this acceptable precision? I think I can hear the test tone change in pitch when speed decreases around .2%, but I'm not positive. I don't notice a difference on the increase side.
I'd really like to determine whether my results are typical, or if my table has an issue. I'm also wondering if arm alignment can impact this measurement. . .I do see back-and-forth movement of the arm as an album plays, on pretty much every album.
