Thank you, I certainly couldn't figure out the right answer without getting the math right (after all, my choice changed from post 18 to post 19). A couple of the others picked C, though. But I'm not that clear thinking.Spoiler for for final
Good work, CaptainEd. I didn't actually expect you to actually implement the method, so your solution makes it all the more impressive. Well done.
