If it works for you, I'd keep it. The thing I'd have to watch out for myself I get tired at the end of my 3rd week and am looking for the 4th week rest week--I'd have to spread my intensity out (which looks like what you are doing with keeping yourself below the supercritical 1000 TSS).
1 I'm just beginning to play with cycles this year. One cycle for me is 4 weeks with 4-5 days significantly reduced volume/intensity at the end. Fitness testing shoots me into the next cycle.
2 and 3 I can't comment on, yet.
4 fishing for redfish with topwaters is great fun.
5 the lady was a man, man?
