I'll add 0.5 sec, or make my aero drag significant, to give me a more realistic prediction.
I'm using an SRM (Cannondale SI model, not sure how precise it is, wireless) to measure power. I was using my best recent 35 second power number as an average, and my best recent 2 second number for 2 seconds (both numbers hit in one effort). I'm not that fast so the AC number didn't make sense to me.
I don't understand the second bit. Are you saying that it's better that the base bar handles not be too low? I was thinking it would be good to match my drop position (BB->Drops relationship) as that's what seems to determine stability under acceleration. I experimented with sprint position on the road and found that having the bars a certain relationship to the BB was the best. Higher up, further forward, or even further back, not as good. On the other hand I have never ever done max effort standing starts so there's that. Only standing starts I've done were for regular long time trials, 16-65 minutes long, so I started pretty gently relatively speaking.
Time for bed, thanks for giving me all these things to think about.
"Time in which power is maximum"... they use 3,7 as default - reality for me is 8 to 9 sec - play with that and check how it changes result.
I use "Time period" 38, if result is slightly lower like 37,6. etc. no that 50" default - this 50" brings time 2 sec down and wrong - I play it in an iterative way until both numbers converge - estimated time and "Time period".
Using my Mexico 2018 Pan numbers (I rode a decent 37,6 sec - WKO image below) I got very near results - 37,5 and 37,8, just playing with 8 and 9 for the peak power time.
