I believe, you were the one calling it pyramidal 
What I am saying, is that most PROs or cyclists with enough time to train seriously do most of their riding at intensities below 75% of FTP or so. In that sense, I agree with polarized approach. I also think that some riding at SS/tempo efforts are also required. Even more of that if target event specifics require it. So, overall, I guess we have similar ideas about training.
I do not, however, want any reader of this thread, come, look at the chart provided from you (I have read the source study as well) and go “Whoah, PROs training distribution is pyramidal and they do most training at middle intensities”, because that would be misinterpretation of the chart. Hence, the same chart expressed as % of FTP to display, that while it might look pyramidal from first glance, in reality it’s not and most training time is spent significantly below threshold.
