Incorrectly marking final bit of show as commenrcial

On almost all my recordings the final short segment of the show is always marked as a commercial. Is there anything I can do to fix that?

BTW, thanks reboot, the last settings I got from you seem to be working failry well... I'd say 80% accuracy.

Using Schoolhouse, (or if you look in the log) what determination is the last block? (Medium, low, too long, or???)
