Based on the 22:22 (which is nearly 2:30m slower than Balarcon's record time) Figueiredo must've done something between 6.5-6.7w/kg. Mind you they did accelerate at Barreiro and pace themselves at Monte Farinha because Moreira was struggling to hold on. I don't think they could've beat Alarcon going full gas but Freddy Watts could've potentially been near the mythical 7w/kg.
DS's saying they were "lost for words" ("""Professor""" Zé Santos from Boavista) and "wanting to stay within the rules of cycling" (Jorge Piedade from Louletano) really says it all.
I promissed you this would still be nuclear and ridiculous. No one gives a single fvck:
