    You certainly have confused me otaw!!

    Applying your formula to the ARQ numbers above and assuming P1,P2, and P3 are roughly equivalent to P90, P50 and P10 respectively I end up with less than the number I first thought of!

    ie ((0.25 x 5.2) + (0.5 x 9.2) + (0.25 x 14.2))/3 = 3.6m barrels

    Or did you mean harmonic or geometric means rather than arithmetic?
