Couldn't agree more.
For me, the best way to work out cockpit size is to use 3 key measurements:
(1) bb height = where your feet are
(2) front wheel height + handle bar height = where your hands are.
You can then micro adjust this with front spacers and different stems.
So, for example, my Faction and Model C both have a 8.75" handle bar and both have exactly the same cockpit size in terms of feet to hands height.
Faction bb = 11.8, wheel size =22"
Model C bb = 13.76, wheel size = 24"
