A typical light twin typically holds altitude quite sufficiently on a
single engine.

For those who can't read that, it's a Barry Schiff articled talking about
flying a Seminole with a SE service ceiling of a bit over 4000'. Of course
he is talking about a feathered and otherwise cleaned up twin, and his
conclusion is NOT that you hold altitude sufficiently, but that the rate
of descent is manageable.
