This is almost always invariably the case and is typically the situation and problem with these sort of "Archicad vs. Revit" kind of videos comparing the two software in a little modeling or speed-modeling exercise.
It's almost always that it's a Revit user, who either gets an Archicad user that doesn't really know how to use the software well or correctly (let alone fast and skillfully), or that they themselves (if they're doing the Archicad part as well), don't really know what the hell they're doing from a workflow standpoint on the Archicad side.
Which is why for the most part most of these videos are incredibly worthless.
10-15 years ago you'd have lots of people volunteering to do the Archicad part correctly, who happened to be expert users or who at least knew how to use the software correctly and skillfully.
Nowadays no one has either the time, the inclination, and most importantly, the motivation and desire.
Taking part in something like this implies you have some enthusiasm about doing it because you understand that it helps promote the software for non-users or Reviters to see how it works well under skillful hands.
That motivation is in dwindling supply among expert and long-term users these days and Graphisoft have no one to blame but themselves for that state of affairs (...if they even care).
So you end up with a lot of these kinds of half-baked poorly executed "competition" videos proliferating the media space these days that serve as nothing more than thinly veiled and poorly concealed Revit promotion videos, really.
I'd love to be the one to point out the 10 to 50 different ways they're doing the Archicad parts all wrong or inefficiently in these videos, but why should I?
Why should I be the one to help out Graphisoft curb this sort of misinformation about how their software should be best used, when they're busy treating my patronage of it, like I'm some sort of redheaded step-child with radioactive Ebola or something?
And that was how I felt TEN years ago.
