I agreed with everything you said until this. I find tempo rides to be very effective. Of course, given unlimited time, one would spend comparatively little of it in Z3 - long z2 rides mixed with HIIT would be the answer. But few people have unlimited time and a tempo hour once a week or so is pretty useful, imo.
