If you ask a question, answer it yourself, and select it as best answer, do you get 22 points?

Question

20 points for best answer, and 2 points for selecting best answer.

Answer 1

I know from past instances of this that you'll only be awarded two points for selecting your own answer to your own question.

There must be an exception in the program that blocks the 20 points if the question's author matches the answer's author, which is fair enough.
