Comment on "modified quantum-speed-limit bounds for open quantum dynamics in quantum channels"

In a recent paper [Phys. Rev. A 95, 052118 (2017)2469-992610.1103/PhysRevA.95.052118], the authors claim that our criticism, in Phys. Rev. A 94, 052125 (2016)2469-992610.1103/PhysRevA.94.052125, to some quantum speed limit bounds for open quantum dynamics that appeared recently in literature are inv...
