Hi. I find it particularly interesting that you say your leg weakness and scuffing are worse toward evening. That's my problem, and I've never been able to figure out how why. I've blamed it on nothing more than end-of-day fatigue, but there are days –– late afternoons, which I'd think would prove cause & effect –– when I've cycled (stationary cycle) followed by some evenings when I have leg weakness and other evenings when my legs feel fine. I find it all very puzzling. ––Ray (@ray666)
