Some counter points: I'm not sure that parallelizing the experiments would keep the same 4 month implementation time frame. It would also fragment the knowledge base, as fewer people would have been working on the one version that gets pushed. I also have my doubts about what happens when two of the experiments seem equally promising. Interesting idea nonetheless.
