Abstract:It is shown by general arguments and numerical calculations that the mass relation among the top-quark and the fourth generation of Dirac quark-leptons in the full four-generation condensate scheme of the minimal electroweak symmetry breaking could be made rather stable for variation of the compositeness boundary conditions if the fourth generation is assumed to be mass-degenerate in the bubble approximation and the mass equation of the top-quark is used. The perturbative theory is argued to be applicable in most part of the momentum region below the compositeness scales even if these scales are now lower. Thus if the scheme works, then the resulting mass predictions of the fourth generation of quarkleptons leptons and the Higgs sboson from the experimental top-quark mass as an input would be reliable and also insensitive to thepossible range 170 GeV-190 GeV of the top-quark mass.
