Wouldn't you prefer (committed + 1) / completed? Or (committed + 2) / (completed + 1)?

In the limit, you want this to approach 1 (namely, you complete more or less everything you commit). A bad situation is where you're overcommitted and have many committed things, but few completed ones (e.g. 10/2), which results in a high ratio. But, with your proposed metric, you'd achieve the asymptotically ideal ratio with 2 committed projects and only 1 completed one, and in fact the global optimum is "I promised nothing and did nothing, yet achieved a ratio of 50%".

Haha, you're right, I meant `(completed + 1)/(committed + 2)`. A value close to 1 means you completed a lot of what you committed, and a value close to zero means you completed a very little. I stole it from Laplace's rule of succession.
