With regard to the actual Bahati video and not SRM data recording... according to the numbers on the screen he's doing 600-900 watts for about 40 seconds prior to the sprint, gets a couple of seconds "rest" while railing the last corner, then does a 12 second sprint with a peak around 1270 and an average around 1100. Those numbers all make total sense.

He says "2500 watts" in the voiceover but he's just mis-speaking, he means 1250 watts. As he says in the narration, he wins the race by how he sets up for and takes the corner, not by outsprinting the field. It's really cool how earlier in the video he mentions trying out inside line on that corner and getting his plan set for the finale.
