I asked for solid advice. Like a tell tell way to do it. Most things I have researched say conflicting things.

There's an art to it. It takes lots of looking and lots of time to get accurate at it and even then there's that (10% according to hatcheries) room for error.
I've only ever known one person that could do it and they tried to show me time and time again and I never figured it out or saw much difference even when it was explained with diagrams.
That was decades ago and I doubt videos would make a difference.
Good luck
