Its more than an academic question for me. My home airport
has a 3 degree runway, and some local airports are even
steeper.

I had to dust off my old HP calc for this and came up with an assumed 3000
ft runway being 157 ft higher at one end than the other?!?. Where is this
"home airport"?

You shouldn't need a calculator for this one. 3 degrees is 1:20. Just
like an ILS glide slope.
