... No. It's half as hard to crack as one that doesn't try 2 passwords on every attempt. Sure, the password cracking program would have to be updated to take advantage of that, but if you think the good ones aren't custom, you're sadly mistaken.
Whether or not that's true is obviously up for debate.
