ive pulled 8 FA, 4 of each print run, and ive seen my friends pulled multiple FA, from different print runs also
the only way to tell which one your going to get is to see what print run your booster is from.
thats where the codes come into play as most of the non coded packs are from the first print run,for the most part atleast. and the coded packs are from the second print run for the most part.
and its just as likely that PUSA printed some more non-coded booster packs in the second print run.
but overall, if you open a non coded booster- itll most likely be from the first print run.
and if you open a coded booster - its going to be a second print run. guaranteed
