I went through a period late june - early august last year when I was without my powermeter. I was still training by HRT.
I think that is what messed with my fitness signature progression, and why I am now seemingly playing with it after every ride.
Do you think I should just go back and have it reseed progression from when I started recording power again? The lapse was almost 6 weeks.
I just want to maximize my training and stop tinkering with it. I realize I can still get a solid workout by doing 20 minutes tests every 4 weeks and adjusting TP, but I would like to use more smart intervals and I think they really depend on a good signature.
