Basically your argument is: if Vingegaard (or anyone really) beats Pogacar, it's just a regular performance. If it's the other way around, it's superhuman.I love Vingegaard I do but he has never showned he is able to match peak pogacar not even before this year which he has gotten extremely much better like you say, but indeed a little bit closer maybe for the fun of it indeed, but also dont forget Pog did the Giro.
He has 2 GT to his name thats it and both somewhat asterisk to both it is what is.
While your theory is likable the numbers are not backing it - he has never produced better numbers forget the TT, he outdid that this year on stage 15 there isnt anything to discuss on every metric and still Pogacar is on a training ride on his wheel not even effected,smiling and riding without no hands, its just mental how much stronger he really is if were beeing real.
There just is a super alien out there nothing else, Vingegaard is still a brilliant rider ofc goes without saying.
Imagine Pogi spending two weeks in the hospital, and having just 6 weeks to properly prepare for the Tour, starting from basically zero. You think he reaches the level he had this year? Of course not. Why is it that for Vingegaard apparently this doesn't count?
