How do I know if my currency is "misaligned"?

A new bill up for debate in the US called "The Currency Exchange Rate Oversight Reform Act of 2011" proposes to fix the US economy by punishing all countries whose currencies are "fundamentally misaligned" (read: manipulated), presumably with respect to the US dollar.

Among the promises of this bill, it also . . .

Establishes New Objective Criteria to Identify Misaligned Currencies. 

Well, that's dandy! I would like to know something about these criteria, however. For instance, in the summary of the bill, there is a link to this article (apparently for support), which states:

First, the United States must, in effect, weaken the dollar by 10 to 20 percent.

It is not clear to an objective reader how this differs from the other currency manipulators presumably targeted by this bill.

I also remind you that these new objective criteria will be used by the same blundering fools who failed to identify the housing bubble.
