I think the power numbers on display are what his meter has. The meters sometimes spike, Most power meters are measuring deformation of some part (crank, or metal strips inside them) and calculating the force to deform that amount and getting the power calculated from that - meaning - a 1/4 turn jump can give a very high real number, but I think he was laying down about the 1250W it showed for a few seconds. And I didn't see him jump.
