Is there any information we can gather about the TCs based on the timing between the messages? I suspect we don't have enough detail to figure out much, but I noticed that #1 and #2 were 3 days apart, #2 and #3 were 5 days apart, and #3 and #4 were 10 days apart. (Also, David Levine said he was waiting for "the right time" to post #5, although it may be cheating to rely on that.) Is there anything to be gained -- even just a prediction of when the next message might come -- from the timing information? I don't know enough astronomy to be able to figure out if this is significant, but might there be some information to be gleaned from it as to the length of their year or something?
