i e, wheels may matter more because they accelerate differently.

The rule of thumb that I've been told goes, "an ounce off the wheels
equals a pound off the frame."

Oh, it's getting even better! The old saying used to be: An ounce off the
wheels equals two ounces off the frame.

But it really isn't. For reasonable wheels and tires, and typical
accelerations, an ounce is an ounce regardless where it is. And yes, losing
5 pounds off your body is the same as getting a 5 pound lighter bike (but a
lot cheaper!).
