Whats your setback like (as percentage of saddle height)?
On the road bike you ride most, what is your setback like as a percentage of your saddle height?
I know that individual body physiology is a good reason for differences but I'm curious.
As an example of how to measure:
my set back 6.1cm/71cm saddle height measured along the seattube
=8.6%
This is only a question to satisfy some curiosities that have arisen with me.

yeah, horizontal distance of nose of saddle to bb centerline, like this image:

this is worse than the other pseudo studies on here because you think its well thought out but the formula itself is flawed.

I don't think it's a perfect formula(it's not actually "mine"), and in my original post stated "I know that individual body physiology is a good reason for differences..." But to that extent, obviously riding goals and style also play in to the equation.
What actually spurred me wanting to ask here is an article from Dan Empfield; https://www.slowtwitch.com/Bike_Fit/R..._Fit_2631.html
Dan apparently has a set of data from Mediterranean pro level riders, and recently surveyed long time road racers who are members of the ST forum. I suspected that the wider variety of bike riders here would result in a wider variety of results. Whereas Dan saw a fairly narrow range in the experienced racers' setbacks, mostly right around 8-9% setback; in what he posted on the ST forum there was a fairly small standard deviation in his data. Even in the few responses my poll has, there is obviously more variety here.
Dan used the results to tweak his fit protocol for road bikes. Starting at about +10% and then moving forward based on feedback.
I know instead of starting a fit conversation, it would have been more valuable to start another aero v. weight thread or maybe a handbuilt v. factory wheels thread or a Caad thread... So many options and I chose something as mundane as saddle setback.

one of a long list of reasons why this is pointless: you dont sit on the very nose of the saddle.

I think we had a very similar discussion not too long ago, but instead of this formula we were looking at the measurement from the nose of the saddle to the bar.

About two thumbs but I don't know what that is in % of height. I can't count higher than two thumbs.
Saddles are different lengths. The distance from the nose to the sit spot varies between different saddles. The sit spot is not in the same place for different people on the same saddle. And so on, and so on...
