I'm not familiar with the towel test. Below is the guide that helped me.

Analog hygrometers are usually off. The one that came with my humidor is off by 5%. I purchased a round digital hygrometer from heartfelt, it's adjustable and works great. I would recommend. Pick up some beads while you're there too.
