Nub and skull theory - intrigued

I'm really intrigued by all these threads I keep seeing, guessing gender with this theory. I won't pretend to understand it myself! I had my DC2 last week and here is the 20 wk scan pic - just wondering if guesses using this theory are accurate!

Nub theory only works for the 12 week scan. By 20 weeks the genitalia are developed so there's no nub to analyse!

Skull theory is a new one on me. It wasn't around on MN when I was pregnant with my first in 2011.
