I wish it was that simple. Every setup is different, although I set the overhang and offset angle consistently and follow the cartridge manufacturer's recommended tracking force. Optimum azimuth varies, even between identical cartridges. And then once in a great while there’s a cartridge that doesn’t measure well and may in fact be defective. Such was the case with a setup I did a few weeks ago, where there was 2.4 dB channel imbalance, and one channel’s crosstalk performance was poor. The cartridge was replaced under warranty, and on my recent return visit the new cartridge measured fine, as expected, and the client is very happy. So I take each setup as it comes, without preconceived notions of how things might go. By the same token my experience helps me evaluate and make adjustments efficiently and accurately.
I hope this helps.
