ICAO Fuel Calculations vs. FAA

There are significant difference in how ICAO determines the fuel required for a 91/GA flight. These calculations are very similar to what the commercial players are having to comply with. The Annex 6, Part II reference is paragraph 2.2 but is reads VERY dry and is without description or insight. The ICAO Flight Planning and Fuel Management Manual Doc #9976 is commercial operations centered but, provides more detailed explanations to the definitions and is a better description of what this standard (and SAFA regulation) is trying to get to.
