IMHO you will never get true consistent speed with a belt drive and will usually have to adjust each time you want to do serious listening (or record something). This is where direct drive turntables differentiate themselves. I recently switched from a boutique turntable to an old DD classic and have enjoyed the peace of mind. There are simply too many variables with belts, such as wear and humidity, which can affect performance and compound. There's nothing like seeing the "lock" signal light up.
One thing that helped was using a test record with a 3.15kHz W&F signal and adjusting speed with it. This gave me the best results, but it is a lot of work and something I found that I had to do too often for my liking. But this is only my experience.
This echoes my experience.
My Michell Gyro SE is speed-adjustable. I'll get it dialed it to a +/- .01 RPM, and then a week later, it will be off by +/- .05 RPM.
I basically stopped obsessing about it and just re-check it every few months or so.
