I agree. However, an uncertainty of ~0,1 MeV is admitted, so I'm still led to the conclusion that only the first figure right to the decimal point can be considered significant. (As the mass formula has been evaluated numerically, i could imagine that these are the precise results of a formula that only approximates reality, pasted into the given tables without any further editing.)
Besides the additional neutrinos, Heim's theory also predicts a neutral electron and some other unobserved particles. Given the success of the other predictions, i would regard this as an indication of incompleteness only - other unifying theories professionally researched can give an arbitrary number of unphysical predictions in their current form, and still they are assumed to be incomplete, and not automatically wrong.
Another example is Heim's prediction of "omicron" particles with mass around 1500 MeV. One of its resonances is at 2137,4 MeV, which appears to be the Ds-Particle discovered by SLAC in 2003, which was found to have precisly this mass.
