  In a recent paper, Wang and Jiang (At. Data Nucl. Data Tables 148 (2022)
101532) have reported data for energy levels, radiative rates (A-values), and
effective collision strengths ($\Upsilon$) for some transitions of five Al-like
ions, namely Ga~XIX, Ge~XX, As~XXI, Se~XXII, and Br~XXIII. On a closer
examination we find that their reported data for energy levels and A-values are
generally correct, but not for $\Upsilon$. Their $\Upsilon$ values, for all
transitions (allowed or forbidden) and for all ions, invariably decrease at
higher temperatures. This is mainly because they have adopted a limited range
of electron energies for the calculations of collision strengths. We
demonstrate this with our calculations with the Flexible Atomic Code (FAC), and
conclude that their $\Upsilon$ values are inaccurate, unreliable, and should
not be adopted in any applications or modelling analysis.
