Exactly Scott. Of course, the biggest advantage of the SCT is its versatility and flexibility of uses, and its size is pretty good too WRT the size of mount needed vs same aperture newtonian.

There' one way and one way only to test a telescope and thats eye up to the eyepiece.
All of these charts and graphs and maths leave me cold.
Astronomy books are the biggest culprits in this regard.

But subjective testing by itself is full of bias and a predisposed desire of what we want the outcome to be, mostly to justify what we have. We must get our bias and predisposition out of the way so that our evaluation is as honest as possible. The only way to do that is backup observations with objective testing and measurement. Subjective testing by itself is meaningless and unscientific. They must go hand in hand.

Sadly, humans are the poorest instruments ever constructed. They are inaccurate, inconsistent, subject to personal bias, subject to professional bias, and subject to peer pressure. That's why scientists dismiss them and why they are given the least weight in a legal proceeding.
