That might be a bit fast for bump starting. If I'm doing pulse and glide, 40-50 MPH is usually where I'd be shutting the engine off, not starting it. That could be why you didn't see an improvement in MPG too. I think it works better at lower speeds. I usually only coast to stops and downhill if it's not so steep that I need to brake. I tried a constant P&G in my old Civic and didn't see an improvement either. It might work better on overpowered cars, or at very low speeds.
