I've read some of the shoulder at 90 degree stuff, and I don't get it as a rule of thumb for many people - too much variation in bone length from person to person. For eample, I think you'd need a longer stem and flatter back to get 90 degrees and an elbow bent enough to protect wrist, elbows and shoulder - and that might put too much weight over the front wheel.
I've read that the 90° rule is between the hip, shoulder, and wrist joints -- e.g., where they put those dots on the video capture fits -- NOT the torso to upper arm angle. Meaning, if you have the recommended 15° bend in your elbow, the torso/upper arm angle would be more like 75°.
