Yeah, it looks like Rodrigo's +4 is a Typo. He should (probably) be +1.
While I am here, I think I should mention that I will be in Japan for the next 16 days. I will probably have more time to post, rather than less, but it depends on where I can find WiFi. So if I happen to disappear, don't fret! I will return.
If I don't return, then worry that I ate some radioactive Fukushima sushi and turned into a giant monster and had to be killed by six guys who formed up into one giant guy.
