Just a quick update. I've heard back from Guinness. They've accepted my application, and have confirmed that it's a "legitimate" application, which doesn't necessarily mean it's a winner, or that my "feat" qualifies as a legitimate record. It just means that they don't reject it outright.
They tell me I'll hear back from them within the next 2 weeks or so. They'll tell me, when they finally get back to me whether or not my feat qualifies as a new world record.
I'll await their response with bated breath. In the meantime, you can check out the video in the sidebar to the right.
