Impressive testing, Tony. And welcome to the forums.  :) I must admit that I didn't bother much with the numbers since experiencing the CTDs due to the gauge itself. Kind of like any key press could end the flight, so that kept me away from doing more than just turning that mode knob.  :-[

The shame is that this gauge actually is a great detail and, if done correctly, would help operating the 737 a lot. Imagine it driving the bugs correctly, calculating the values beforehand and allowing a sneak peak on the flight progress.

I saw the competition adding a FMC for the lateral navigation (maybe even vertical) but leaving the PDCS out. So that's where the CS could shine but currently doesn't. Well, one would have to add all the user mods on the current FDE of course since the default basis is off the charts, literally.
