  I present a selection of CP-PACS and UKQCD data for the pseudo-Goldstone
masses in $N_f=2$ QCD with doubly degenerate quarks. At least the more chiral
points should be consistent with Chiral Perturbation Theory for the latter to
be useful in an extrapolation to physical masses. I find consistency with the
chiral prediction but no striking evidence for chiral logs. Nonetheless, the
consistency guarantees that the original estimate, by Gasser and Leutwyler, of
the $N_f=2$ QCD low-energy scale $\Lambda_3$ was not entirely wrong.
