If you're certain there are no start early/end late minutes on the Earl
recording rule, that means that you have a different rule that's
matching instead of the one you think is matching.
Delete the Earl rule ("Do not record"), then see if it's still scheduled
to record. If so, find the rule that's matching it and fix it. If not,
then re-add the rule. It will likely record properly (meaning that the
other rule had some start early/end late settings).
If with the new rule, it still records wrongly, it's probably either a)
EIT data that's messing with the listings at the last minute or whatever
or b) broken clock/timing on your system--use NTP and make sure you
don't get strange things like, "Clocksource: tsc unstable," or some
other telltale sign of broken timing on your system.

I'm guessing you're thinking it's recording less because when you play
back the 1-hr show, the OSD says "01:20 of 50:14" or something. If so,
that's just a display-related bug that affects the calculation of the
duration of the show--it actually recorded for the whole time. It's
also /extremely/ low priority to fix because it's a huge fix with a
