I'll try a rough estimate, HR Z2 for me has been similar to Power Z2. At 35 I did a lot of Z2, roughly 42x16 or 15 on the flats, so somewhere around 20-21 mph (210-220W roughly). That would put my FTP back then at best 290W & at 150 lbs just a tick over 4 W/kg. Nothing earth shattering, about what you would expect for a field fodder 2.

240W FTP is the best I've tested recently so down 16% in raw watts. Most of what I've read says around .5% per year so I'm tracking pretty close to that, although it has not felt like a steady decline. My current Z2 target is 160-180.
