Lolololol. So I'm looking at my power curve on intervals.icu and they're telling me that my power profile is "all-around" (code for "ha ha - you fat ****!" I assume) and my the top end is looking... low. So I do a little digging, looking for individual activities where I know that I exceeded X watts for Y seconds. And I start seeing these weird little symbols. wut. Clicking on them reveals that I exceed their expected power curve for me, based upon my FTP, by more than 20%, so they kindly "corrected" the spurious data for me.
