You sent two different runs: the starting configuration for the job running
on 70 CPUs was closer to convergence than the one on 24 CPUs. Of course the
former performs more iterations than the latter in the same maximum allowed
time.

You shouldn't use 'cg' diagonalization unless you have a specific reason to.
