According to my calculations, he did today:
Isaac del Toro | 81 (-5): 6.63 W/kg for 25:19 on Jebel Hafeet.
This is a similar level to stage 3 on Jebel Mobrah (82). Of course, the pacing today was much more irregular, so I consider today's performance better.
But I am still not sure if it is really a qualitative leap compared to last year where he also did several performances of around 80.
He is still missing that one extreme performance that would make me absolutely sure about his climbing potential. Nevertheless, his acceleration, sprint and consistency over the whole season make him a great rider already.
