For alleged exponential extremes of fermion mass spectrum for very early universe, since (?) SU(3) is still suitable, might one also have an increase in rate of quark flavor changing, and of rate of quark gluon emission and absorption, and of rate of gluons’ interaction, and more so for massive gluons? Hence a more entropic generation descriptiveness?
Also recent pentaquark discovery would be consistent with higher generations i.e. fermion mass spectrum. TMM
