I will say what I've said in public, even though I really don't think it worked out well for me, but it's still what I believe:
What you include in your course ratings says more about
who you are and
what you value than anything about what you think of any course.
I think it's pretty clear that I have heterodox views about golf course rankings. I've written about why I think collective rating systems are
mostly useless, and that course ratings are more useful (and arguably more interesting) when they are specifically based around an individual's preferences, rather than and objective sense of what is good.
I value many things that you've not included: accessibility, stewardship, a sense of value in cost but also in historic, architectural, or agronomic merit, environmental impacts, and the golf course as a place, more than just the course itself. However, I don't think you or anyone else needs to include those things, because your audience will appreciate your take, exactly because they gain something from your opinions on things that you value (not on things I value).
I think you have a well thought out system, and the idea that you're taking on public access course will be very helpful to the most people. I'd be excited to read some of your thoughts and impressions of courses when you start writing.
