This well precedes your fine review, Raytracer. We're simply reiterating the conclusions of past debates to those who were not present at the time (as is so often the case). Our amiable and enthusiastic UCS fanatic mortesv committed an honest error in enlightening another member (with the best possible intentions), so those who knew a thing or two about studio models and MOCing (in this case Anio and Aeroeza, though I often join in) felt it would be helpful to share their knowledge.
The question of what exactly UCS denotes is another one of those past debates (one probably older than this site, in fact), so I won’t touch that statement, though I will say that as a FOL you are most justified in your satisfaction with this set. We accuracy sticklers are in the minority, and as all this is a harmless bit of lighthearted nitpicking, we only ask that you let us have our fun.
Speaking of which, it’s wonderful that Aeroeza has provided us with this ‘geeky and industrious’ construction illustrating that the angles at the top and bottom of the Executor are in fact congruent. In fact...

Though that isn't the original.
Anio himself has admitted that there exist certain significant inconsistencies between his creation and the studio model due to the limitations of the medium, personal preference, and other factors (in terms of height, for example, the belly of 10221 is actually closer to what’s seen on the source material than that of Anio’s Executor) , so I’m not quite sure what you mean by “remarkably consistent”, but in any case, interesting study. I wonder how Lasse’s would fare against the original...
