Query: New experimental data for the quarks mixing matrix are in better
  agreement with the spin-charge-family theory predictions   The spin-charge-family theory predicts before the electroweak break four -
rather than the observed three - massless families of quarks and leptons. The 4
x 4 mass matrices of all the family members demonstrate in this theory the same
symmetry, which is determined by the scalar fields: the two SU(2) triplets (the
gauge fields of the family groups) and the three singlets, the gauge fields of
the three charges (Q, Q' and Y') distinguishing among family members. All the
scalars have, with respect to the weak and the hyper charge, the quantum
numbers of the {\it standard model} scalar Higgs: $\pm \frac{1}{2}$ and $ \mp
\frac{1}{2}$, respectively. Respecting by the spin-charge-family theory
proposed symmetry of mass matrices and assuming (due to not yet accurate enough
experimental data) that the mass matrices are hermitian and real, we fit the
six free parameters of each family member mass matrix to the experimental data
of twice three measured masses of quarks and to the measured quark mixing
matrix elements, within the experimental accuracy. Since any 3 x 3 submatrix of
the 4 x 4 unitary matrix determines the whole 4 x 4 matrix uniquely, we are
able to predict the properties of the fourth family members provided that the
experimental data are enough accurate, which is not yet the case. We, however,
found out that the new experimental data for quarks fit better to the required
symmetry of mass matrices than the old data and we predict towards which value
will more accurately measured matrix elements move. The present accuracy of the
experimental data for leptons does not enable us to make sensible predictions.
