Here is a deeper dive into stem length not taught in bike fit 101. See below pic marked up by bicycle guru Dave Moulton.
Dave believes a common mistake is to position the handlebars too far away from the rider and too high. What this does as mentioned earlier is rotate the shoulder blades up which puts more pressure on the base of the neck when the neck is extended viewing the road ahead which leads to fatigue and pinching off the blood supply
Based upon his thousands of fittings, he believes the hands on the hoods should parallel the line intersecting the pedal spindle at 3 o'clock and the the hip bone. As a result, his critique is this rider needs a shorter stem with less rise.
