If you want to compare your power profile on both types of bikes, just do an all out 5 minute effort, a maximum sprint effort, and a proper 20 minute test on both platforms. The easiest would be to open two XERT accounts and let it calculate your power duration profiles. Then cancel the accounts. They may offer a trial. GoldenCheetaah does the PD curve too but it is not as easy to use but is free.
I completely disagree on the platforms being equal. The biomechanics and lung perfusion profile between the supine and upright position varies significantly and are key reasons many/most bent riders make less power. The research data is out there and it does not take a lot of connecting the dots to see. A Pro with 400 watts is not likely to make 400 watts on a bent even if they stuck with it long enough. It is possible but not likely. Would he eventually make 350? I dunno. Try getting them to stick with it long enough......LOL.
WRT to Borrego Springs, Marco B. averaged 301 watts for about the first 125 miles on an upright and most other DF racers were around 250 watts or more. I seemed to have remembered that you (175 W), Jim, Willie Hunt (145 watts) and Kevin G. (167 W) were under 180 about watts and checking the actual Strava data confirms that all the bent riders were in the 145-175 watt range for the first 125 miles whereas similarly placed upright riders were averaging 250-300 watts, which of course clearly demonstrates the superior aerodynamics of the bents.....we all know this. Even on the first 18 mile lap of the race, one can look at the KoM data. I think Jim is 3rd out of all riders and he only needed 207 watts. Does anyone think he was soft pedaling? I doubt anyone would think that you or Jim did anything other than your very best. Almost every bent rider makes less power than on an upright but they go much faster on the flats and slower on bigger hills. The bents were slower than the uprights on that little hill in Borrego. This is just the way it is for 99.44% of us. From my old upright perspective, 145-175 watts is pathetic for 5 hours if on an upright. It really is. At 57 years old, I used to hold 220-230 watts for 8 hours and over 200 watts for 12 hours on an upright and I am no place close to that on a bent.....nowhere near that. On the other hand, I would be delighted to hold 175 watts for 12 hours in Borrego later in October but ain't holding my breath on that one. Not to be too obtuse.....175 watts for me would destroy the 12H bent record sitting at 248 miles and just under the upright or overall record of 285 miles. None of this answers whether a 400 watt pro could do 400 watts on a bent and frankly, we will never know. We'll just have our opinions. Mine is clear.
