though - ideally - you do not care CPU time, PRECISIOn is not always a
fully safe choice, assuring that all the physical processes important for
your case are automatically taken into account. They are different
according to what you are interested in.
In general, I would suggest to adopt NEW-DEFA (no DEFAULTS card needed)
and to explicitly set electron/photon thresholds by EMFCUT, possibly
coupled to EMF-BIAS to avoid CPU time divergence. In addition, you should
know if it is worth for your purposes to activate processes switched off
by default (e.g., photonuclear and nucleus-nucleus reactions - crucial in
specific cases - ) or to change other default thresholds (DELTARAY,
PART-THRes ...).
Hope this helps
Ciao
Francesco
