I tend to position my cleats a bit rear of the ball of my foot, so these calcs seem to make sense as a starting point.
OTOH, Loose Chain's method gives me
90cm
I suspect he should be dividing PBH by 109% instead of multiplying. That gives a result of 75.7 which seems more reasonable. But then again, I'm not professing to be the engineer, scientist or math lover that he is.
Your sarcasm fit you, I imagine you are that way in yiour daily life, the rest I will not dignify. Your issue is you are crossing up the methods which is the result of not reading fully the posts in this disjointed thread. Google is your friend, though my info comes from books, not the interweb. The 109% Rule is from the pedal surface to saddle crown. The Lemond Method is from BB center to saddle crown if memory serves. If you need to to find a link that explains it better than I have let me know, without the sarcasm. If I have confused you, I apologize. To make it all good for you, I/we, need to know what exactly you are measuring and from where.
