Claim:
1. A fueling method comprising: commanding a stop of fuel flow into an accumulator; sensing a fuel pressure in the fuel accumulator; following said commanding, delivering a quantity of fuel from the fuel accumulator during a first injection event and a second quantity of fuel during a second injection event subsequent to the first injection event; acquiring first fuel pressure values indicative of the fuel pressure during a first intermediate pressure period extending between the first injection event and the second injection event, the first pressure values representing contiguous oscillations, each of the contiguous oscillations defining a single cycle window; calculating a single cycle window pressure for each of at least two of the single cycle windows; and calculating a first pressure for the first intermediate pressure period based on the single cycle window pressures of the at least two of the single cycle windows.
