I need to learn more about periodic error. 50 arc seconds sounds like a lot. How long does one period of the periodic error oscillation take?

That's pretty typical for these very small format mounts. Remember the worm wheel is a fraction of the size of a full size EQ mount so you can't expect the same level of precision as you scale everything down. The period (which is mentioned in the article) is ten minutes.
