Since this penalty has existed at least since September 23, 2005, I'd say 16 months is long enough to wait...

The penalty is plain enough. Occasionally for some terms you don't go all the way to the back, like a search for the entire title, or the title plus the H1 in quotes, but for the most part a non-spam page gets pinned in the last 100 results with other penalized pages.
