That doesn't seem to be the right way to look at the numbers.  In a local system,  there are two different repositories enabled by default - Fedora and Updates.  Fedora repodata is about 40MB but only expires every 7 days .  The updates repo is about 32K and relies on the default metadata expiry period which is 2 days.
