    40 0.95 0.81 0.9
    50 1.0625 0.90 1.125
    57 1.14125 0.96 1.2825
    70 1.2875 1.08 1.575
    79 1.38875 1.16 1.7775
    80 1.4 1.17 1.8
    86 1.4675 1.22 1.935

    The above chart shows 3 different ways of calculating weights.  All three use the prototype length.  The first is the NMRA formula, the second is by an individual and the third is the Belmont Shores Club.  The difference at 40 feet is almost negligible, but become more significant as the length of the car increases.
