Blown away by your eagerness to attempt so many different avenues of edge maintenance.
I'm new also. 5th shave tonight. I definitely have stubble left over and clean up with a DE pass or two. I'm considering that acceptable until I become more comfortable and efficient with my SR. Then I can begin doing more passes in different directions. For now, I like the challenge of slowing down, remembering to stretch my skin, check my angle, and go slow while trying to figure out how to reach every area of my face with the SR. It's definitely a challenge and a learning process. My expectations are low as I understand that this is a learned skill over time, and gained through practice and patience. At least this is my current perspective on the act.

As for your situation. I can only assume that you're experience is a result of dulling the edge in one form or many. Professional honing only exists because there is a demand for it.

So... My inexperienced suggestion would be the same as the others. Send it out for professional honing. Once you get it back, shave with it for a gauge of sharpness. Then maintain the edge with a strop free of pastes.
Accept that your shaves will leave a bit to be desired, though you can finish off your shave with another razor option for a satisfactory end result.

Most importantly, don't give up. You started this with interest and motivation. Learn from your attempts thus far, adjust, and move forward.

Hope to see you make progress.

Cheers!
