I went ahead and marked up the second chart you posted.
Maximum effort, 122 RPM for 20 seconds. That is pretty fast.
And, what do you know. Pushing down with a peak of about 60 kilos force (132 lbs), and pulling up with a peak of about 5 kilos force (11 lbs), or about 8.3% However, it may well be significantly more than that as one can also consider the unloading power (weight of the leg), if he is standing, or close to standing, then that added off-side weight can be more or less added to the on-side weight. Less so if he is sitting, but there may be some reciprocal force even while sitting.
The power stroke is also generating power over just over 50% of the stroke which isn't bad.
Anyway, tell a sprinter that you have a suggestion of increasing their power by about 10%, and do you think they'll ignore you?
How many fancy Titanium parts is that worth?
