Well, I adjusted the cleat a bit, I got on the bike, pedaled backwards while paying attention to my knee, and it felt like I was "tensioning" towards the inside at bit...so I lessened the angle between cleat and centerline and moved it outboard a smidge...

I got back on and it felt, well, I felt nothing, which is better than what I felt before, so, I gotta get out for a relaxed ride and see. Left knee is great...
