Hi,
You are absolutely correct. We know too much.
That's why I always recommend Ed Weiss's Book the" Queen and I",to new
beekeepers. It's a simple how to book , that covers the basics with
sketches and drawings from assembling the wood to how to harvest.
 
I don't know a beekeeper who follows any rigid rules, but the good ones
have a foundation of fundamentals to fall back on. I keep this book around
for reference and use it as a refresher from time to time.
 
Regards,
Henry
