That's very true, but who can really say what's the real value of the peso? Are they close to achieve it? Will they stop devaluating once they are there? Currently all type of foreign transactions are rated at no less than 9 (w/35% tax) and it doesn't seem the government has reach the value they want to hit as they keep pushing it every day, a few cents at a time.
The question is of course how much further they want to devaluate, so at this point all we can do is guess using its past behavior.
