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.
