If you spend as much time with Squid as I have you probably will, if not
more..

Again, it depends on your refresh_pattern settings.

Only if Squid sees that the response will be considered fresh for more
than 60 seconds, or if it has revalidation headers allowing revalidation
(mainly Last-Modified) will it get cached.

So refresh_pattern is used both to determine if the response should be
cached and to determine if a later request can be satisfied from the
prior cached entry.

If there is no matching refresh_pattern then the builtin defaults are
used (min=0, percent=20%, max=4320)
