Obviously, with a round trip the uphill and downhill portions are mitigated. However, this would be an interesting data point. Since from my experience, conventional non-hybrids do worse. The downhill coasting doesn't seem to compensate for the increased consumption going uphill.
I can say for a fact, by gauge in vehicle, that going uphill takes away much more mpg than when coasting/driving downhill. You can really see it drop when going uphill, but when it climbs, its much slower to do so. All this assuming the gauge is pretty accurate.

I switch back and to from the mpg and watch the gas/electric to the wheels and most always its getting power from both. Obviously, its not giving any electric power when climbing a hill of any height/length. But on a fairly flat surface, it does show that its getting power from both.
