i don't think he is lost, at all.
he just wants "data" when it probably doesn't exist.
especially when all the manufacturers have drilled into people's heads
to only shoot fresh film, buy fresh film &c.
the funnything is that you could have some great film
but not all the film will be great even from the same purchase,
some may end up being crap and youwon't know until you spend your energy exposing it
and then processing it.
the great film hoard reminds me of the tulip frenzy of the 1600s
if it makes you happy, that is all that counts !
