I feel compelled to admit that something over a hundred of the checks on day 14 were me after I gave up all hope of figuring out the elegant solution and just started counting up from what I had come up with as a lower limit. I really, really wanted a go at the logic puzzle.
At least my failed attempt to figure that one made me realize that I needed to change my answer to day 12.
