There is a problem normalizing q charge and m mass.
(v2t+v2s+v2rg)+(v2tc+v2c+v2rc)=c2 may also be wrong for the same reason.
We should have instead.
(mv2t+12mv2s+12mv2rg)+(qv2tc+12qv2c+12qv2rc)=c2
where c2 still represent a constant.
The kinetic energies along the time dimensions are without the factor 12 (From the post "No Poetry for Einstein"). In the case of, g the factor Go took care of this discrepancies. Both grc and grg also accounted for the value of 2.
Hold you horses! And if however, numerically,
|q|=m
for a basic charge, and then with changes made to the value of εo and Go. We would still have a valid system of equations.
Early posts are still correct as constants Go and εo absorbed the discrepant value of 2.
