This is a thought-provoking and well-executed post. Thank you, as I've learned a bunch!

I'd like to double down that it is indeed imperative to not only post regularly but at the right times,

Posting time and schedule is your first tip for maximizing ROI. Experiment and find the best time to hit publish, then create a schedule and stick to it.

May I suggest trying this tool SteemActivity to track activity and help determine the best posting times. @jerrybanfield provided this guide to show how it works.

I can tell you put a lot of time and energy into this. You definitely have the right attitude to succeed! Followed and looking forward to your next posts! :)
