Points to note: Curve in back - need to get that straight and 64 down to 55. Foot 98.3 down to 95 and 144.6 up to 150. Foot at top of stroke -as close to 90 as possible as it pushes the pedal over the TDC.
Basically - not flexible enough. Need to do more stretching: hamstrings/calfs too tight. And need to push chest forward to straighten back.
If I can go back a couple of steps. I assume all this data is after they change your seat heights, stem etc? Did that have to change much from your original? Also, how did that spreadsheet compare that I sent you. (Interested to see how close it comes). In regards to the 144.6, is that not the angle of your knee? Seat height? Understand the rest ie back and foot being flexibility of the back and calfs.
What your looking at is my final bike setup. What your reading in my comments is where I need to get my body to optimise performance. I can get the 64 down and back straight simply by pushing my hips forward - thats a simple posture thing, much like slouching in the chair at work. Same with the feet, it easy to 'pull up' from the ankle but you should be pulling up from the cleat.
I had been moving my position from where it was to match the MASI. Wrong. Idiot. Moved it all back! I have a seat to bar measurement, a seat to c/l BB measurement and a seat setback measurement from the c/l BB.
The best exercise for correct push and pull. 1 - a bike which monitors pedal stroke ie WATT bikes 2 - pedal with left only then swap to right, this is very taxing but immediately you see how awful your 'pedal circle' is as the noise from the bike is bang (push) bang (slack) bang (push) bang (slack) - thats one rotation!!
That's committment. I think that setup would be well worth it. As for watt bike I have ridden them a few times and I spend all my time trying to balance left and right leg power and then trying to balance the output circles as my right leg dominates. I figure if I ride it continuously over a three to six month period I might the adjustments might become more natural.

Then I just have to sit properly.
