We numerically study the regularization dependence of the upper bound on the Higgs-particle mass MH(phys) by varying the lattice type and interaction. Computing f and where the scalar mass is 1, we find the bound MH(phys)<620 GeV. However, there is a small but systematic increase in the bound as the coordination number of the lattice increases. Hence, it is not meaningful to quote error estimates on such bounds.
