I was going to say that you must be disappearing but I survived 24 years of Service at 10st 4/65 kg at 6 ft.
Always got the peche ripped out of me for being so 'lean' but now I'm the one who's laughing.
Put a stone and a quarter on since then and now I am a fat 32" waist.
On the watts side, I occasionally get 1000 watt spikes but they are down to slope transitions and BSim or the BKool power start where you can wind up to 110 rpm on a 52/11 before the resistance kicks in.
Didn't Kwiatkowski hit 900 watts attacking on the Poggio in Milan San Remo this year after 280 km of racing.
Surely it's possible for an amateur to do that fresh over a few km, NOT.
Even Forstermann couldn't sustain that sort of power, 1000 watt (That's me standing next to him before I won Drag Race last year).
Watch the vid of him cooking toast (almost) on a 3 KW Toaster.

The toast was not too brown mind, wimp!
