This for me is the great thing about this bag; when compared side by side with bags of the same temperature rating in the laboratory, then it will come out as a slightly heavier bag, for the same warmth rating as a truly minimalist bag with the same level of down filling. However, in real world conditions, when conditions are typically damp from condensation, then the Epic will continue to keep you warm while the others will collect moisture and lose their thermal insulation.
The ability to use this sleeping bag out under the stars without a bivvy bag is a big bonus and great for an expedition race, where you can pretty much sleep where you like.
For info, Macpac have had their bags tested to European Standards and the temperature ratings come out as such:
Comfort: +7oC
Limit of Comfort: +3oC
Extreme: -12oC
The standard size bag supposedly fits up to 185 cm tall folks, but I'm 186cm and didn't feel cramped. It is available in an Extra Large size which fits users up to 200cm tall and is marginally wider too.
