Seat tube angle to center of bottom bracket distances for different leg lengths ?
Are there any charts that show for different seat tube angles and different leg lengths (upper and lower leg leg lengths) where the ball of the foot ends up on the pedal stroke?
this one is difficult for me to put into words but let me try a description: I want to get a Surly Disk Trucker for a 62 cm frame it has a 72 degree seat tube angle. Is there any chart that shows for a particular leg part length how far back the saddle should be behind the center line of the seat tube to get the ball of the foot over the center line of the crank

I want to ride in a nearly upright position and will adjust stem and handlebar selection to get me well above the saddle height to get an upright position.
My premise is that seat position should only be used to adjust where the foot is over the pedal and not to adjust for reach length.
I need an engineer to do some math for math for me
