This is difficult to give a straight answer to, since the grid is
generated by an adaptive algorithm that aims to integrate a model
integrand correct to a target accuracy. The accuracy can be specified
on the THR subcommand of GRID, and the default is 10^{-5}. There is a
further complication in that the adaptive stuff is by no means optimal
and the actual accuracy obtained might not be this number

Yes, that's right:
geometry={f;h,f,1.728}
rhf
grid;print,grid=2
dft
