Now this is not at all conclusive evidence, but in my auto P&G got me about 15-20 % over EPA while steady speed got me about 20-25% over. I think P&G has more potential for better fuel economy because the power is being produced more efficiently at high torque and low rpms, but it is much harder because it requires a lot of active driver participation and it's easier to brake more or go faster. But I totally agree: test it out with your own car and see what you get, but be willing to give P&G a second chance if you don't get good results the first time. It's a much harder technique to master. Flat land and long trips and traffic lend themselves more to steady speed while hilly driving and shorter trips and little traffic lend themselves more to P&G. And there's no reason why you can't stay in drive, P&G, and prevent downshifts. Just change the speeds you pulse and glide between. I personally have found that (45-50)-55 MPH P&G works best for me
