A custom CoC value may be appropriate for eagle-eyed Mooses but using a
more stringent CoC is typically not done for large prints (larger than
8-10" vertical).  The CoC makes assumptions about visual acuity but also
makes assumptions about viewing distance.  A letter size image or
smaller is assumed to be viewed at reading distance and thus merits a
CoC consistent with visual acuity at that viewing range.  But the
viewing distance assumption is also that larger prints are intended to
be viewed from larger distances such that CoC's acceptable for letter
size images also tend to work for larger prints.

Consider the golf ball size pixels of truly large billboards.  They're
not designed for scrutiny at book reading distance.

IIRC Coc value can be inputted to
adjust for Moose vision or larger print intent.
