Question ? about Pulse and neutral coasting

I've been doing what i call pulse and neutral coast down hills or slight declines. Say i'm going 40mph i will see a slight decline/hill coming up and i will "pulse" (50-70% throttle) to about 50mph then coast in neutral with the engine on until i get back down to 35-40mph. I also do this on the highway I will be going about 60mph see a hill and "pulse" to 70mph and then coast in neutral down to 55-60mph. I will not pulse if i dont think that the coast will be long enough, that is why i pretty much always do it downhill. I've been doing this since i started hypermiling. I dont see how there could be much benefit from pulsing and then coasting on flat road, or am i wrong? I drive mostly highway and i am consistently seeing 40mpg. My question is am i wasting fuel by pulsing and then neutral coasting? Should i just coast down from the speed i am already going? Thanks in advance
