Cordially,
My initial impression is this - we know that some of these things are the product of intelligent agency. Specifically, 1, 2, 5, and 9 were produced by humans, and thus must be the product of intelligent agency. But the problem is, the answers given in those cases were inconsistent - you determined 1 was designed, 2 was not, 5 was, and 9 wasn't. Or, more accurately, in the cases of 2 and 9, you were unable to conclude that they were designed artifacts, when we know for a fact that they are.
This does not really inspire confidence in the design inference, as I sure you can imagine. After all, if it has what appears to be a 50-50 shot with artifacts known to be the product of intelligent agency, how can we have confidence in what it tells us about artifacts that we don't know about?
