As to Zone 4, I tend to do them just over FTP and for 8-10 minutes on a certain climb. But rarely do those but sometimes.
I tend to agree with this. I'm actually surprised someone that assuming their ftp is set correctly and is busting a 1000 TSS/week has to ask this question. If I were spending that amount of time/effort I would make damn sure it was spent perfectly.
Z4 is pretty broad, from including high quality sweetspot all the way to your 20min
PR power level. I personally feel like reading Slowtwitch and places is that you go for the "more time" earlier in a training cycle and go for "more quality" that is event specific closer to the event.
So for TT for example, you might try to get in a LOT of Z4 sweetspot time earlier in training. Like, a whole lot. Then closer to the event, dial it back to 2x20's, 3x15's, under/overs and such. My Z4 is 40w wide. There's a lot of variability in workouts you can design or leverage in a breadth of 40w. From 2hrs down to probably 35min.
The answer is "it depends" on the phase of training IMO.
