Cosmographic constraints from 106 FRBs on H0, q0, j0 depend sensitively on whether a Gaussian or quasi-Gaussian PDF is assumed for DM_IGM and on whether the baryon mass fraction is fixed or free.
LOFAR2.0, FAST Core Array and BINGO are forecast to bound f_PBH < 0.16 (M>1 Msun), <0.39 (M>10 Msun) and <0.39 (M>0.1 Msun) respectively from null FRB lensing.
