Right, so you are just saying no one really understands how NHEJ works at this point.

Have you considered that mechanism (NHEJ) is not even necessary to explain the rise in proportion of mutant cells after the CRISPR-Cas9 treatment? Because while it may happen to some extent, I do not think that is the simplest explanation for what I have seen reported.

I've been thinking this for awhile now, but never bothered to really write it up and keep track... you can check the discussion here (there are some other posts about CRISPR-Cas9 strewn about that thread as well): https://news.ycombinator.com/item?id=14014098

I have really only read papers other people bring up in conversations online or that get media coverage I come across on this topic. But every single paper I looked into has reported results that fit my explanation just as well as , or even better than, the NHEJ one, and this has been a couple years now...
