True story.
We were specing out a new heat exchanger at my old job. There were three of us, my boss (40 years of experience), an intern, and myself (8 years).
My boss looked at the ceiling for a minute and said “Size X”. I noodled a bit and said a little bit more.
The intern spent all day doing the equations, and came back mad as heck that we were right!
Rules of thumb can get you close enough for a lot of things!

Experience has it's own power. I was remodeling and hired an older guy to set some windows for me. He walks in, takes out the old window, sets in the new window and starts shooting nails
"WOAH!!" I say, "aren't you going to check for square and plumb?"
"do you have a square and a level?"
"Sure" I say
Then check it."
Absolutely right on the money. He was there for the whole week working that room. I never saw him use a square or a level yet everything was absolutely perfect. He'd been doing it for 60 years or so and knew what square and level looked like. (And yes it really teed my off :^) )
