By accelerating at lower loads you reach your target speed less quickly, keeping your engine in a less efficient mode for longer. This, as you have noted, will give you less time to coast so don't be afraid to step on the load pedal a bit, it's good for you.

As an aside, I raise an eyebrow at your hill technique. If you can coast up a hill whilst retaining appropriate speed then good on you but you shouldn't be accelerating downhill, this is expending petrol when you could just be letting gravity do the work. Once again, don't be timid about giving it some boot on the way uphill, your FE numbers will thank you.
Well that sorts it out. I was always stressed on not jack-rabbiting (still a no-no), but unfortunately (and apparently) went to the other extreme. I hadn't thought my engine would do better at 60% than 40%. My motivation for hills was also the same, try and not work it to hard up hills and let it go down hills easy. Thanks for the clarification.
