Some confusion over the last 4 board changes, here is what it should be after going through them:
Codename 47 
Silent Assassin [47.5]
Blood Money 
Season One [48.5]
Just as an aside, I would prefer if people do it the way I did in the example in the opening post. Ideally, you want to do the sum in your own post, the next poster shouldn't be doing the sum for you in their update, only the change they add.
