Query: Comments on `Systematics of radial and angular-momentum Regge
  trajectories of light non-strange $q\bar q$ states', Masjuan, Arriola and
  Broniowski   Masjuan, Arriola, and Broniowski [Phys. Rev. D85, 094006 (2012)] claim that
the slope of the light-quark radial trajectories is 1.35 +- 0.04 GeV^2,
disagreeing with the Crystal Barrel value 1.143 +- 0.013 GeV^2. There are
defects in their choice of data. When these defects are revised, results come
back close to the Crystal Barrel average for the slope. A revised average value
is given here.
