I'm just saying, I genuinely have little idea how hard I'm pushing and it's been put to me before that I'm underdoing it, sometimes by a lot. For me it is just hurt and not hurt. I cannot distinguish really at all between 60% MSHR, 80% and 90%, I haven't got a clue, especially if I switch into a higher gear where it'll hurt anyway. I found the same thing with other people I didn't ride with where they were apparently even bigger wusses and would complain about it hurting a lot trundling along at 10mph although this might have been true because their HR was about 30-40 higher than mine for totally normal activites and spiked like crazy.
