I've been studying this example as I'm planning on drawing on it and citing it at an upcoming seminar I'll be giving (maybe I should post about it in Discourse, in the spirit of this recent comment). I have emailed author @sylee30 with a question I may have figured meanwhile...
Anyway, I'm suggesting the following edits after running the R code and considering that 'knowledge' is used in an abstract way (knowledge is represented by attribute/skill mastery).
