This seems like an egregiously high estimate. Ferrari Formula approximates it at 7.06, that‘s a massive difference.

I guess due to riding alone all the time 7.06 w/kg could be upped to 7.15-7.2 w/kg.
2000 m/h of VAM for 17 minutes (or 1950 m/h of VAM for 19 minutes if shallower part is included). Obviously it's great climbing but didn't our experts expect even more during this TT?

Doesn't the standard formula already assume no drafting?

My personal suspicion anyway is that a formula that hasn't been updated since the 2000s is probably overestimating wind resistance, even for a solo rider as unaerodynamic as Pogacar.

That said, Vingegaard and Roglic were on full TT setup, so the W/kg gap should be even bigger than what it was here.
