How often do people run automated jobs here? I was planning to add this to windows scheduler, and let it kickstart at night... weekly? or daily?

I would say that running P once a month should be more than for most people, but it really depends how much you use Kodi, and what you use it for - if much of your content is consumed online and/or via add-ons (YouTube etc.) then it's likely you will accumulate bloat (ie. thumbnails etc.) in the Texture Cache more quickly than someone who mainly uses a local library of content.

Use c whenever you add new content.

Use Xd and R whenever you experience weird problems with the cache.
