James, VTA is important to get close to a 92.5º I believe it is... but what's important to note is the tip when inserted into the needle is not always, or maybe typically, perfectly aligned. You can use a microscope, or adjust VTA for sound if you don't have one. The azmith is complicated involving test records.
This has happened to me, where VTA adjustments greatly improved accuracy by adjustment over the "recommended" setting that didn't account for my particular needle to tip being slightly off. For this reason I actively avoid turntables that make it difficult.
