@AdamJamesMason I think there is a lot of harm to be done to a wbeiste by using the disavow too eagerly. Thankfully I haven't had to utilise the disavow tool for any other client, i wanted to see the effect first on a client. I'm looking into testing it out again when it's needed.
Yeah, it makes sense to disavow on both platforms. It's not likely, but i wouldn't rule out some kind of shared data.

Nice round-up. From my own experience and talking with other consultants, there is definitely some correlation with successful disavow efforts and Penguin. I saw a significant impact in the rankings of a client, with a lot of their links cleaned up through the disavow tool a few months ago. There was no real impact until latest penguin update and others have agreed that the penguin updates refresh the disavow requests.
p.s. One thing to add that you haven't noted is that when you disavow links through Google Webmaster Tools, that you also disavow the same links through Bing Webmaster Tools. I can't get my head around why people wouldn't naturally do this.
