Really? Let's check for this time around. Date stamp of my #77 - 8:42AM. Date stamp your response in #80 - 11:02AM. Massive improvement - less than 3 hrs reaction time. But that's still weird - because you have been logged in all that interval. No don't bother trying to explain it. A uniquely Daecon thing I guess. Given how long you have been here at SF and how many scores of times you must have been exposed (and not just here at SF) to the notion of HR from BH's, it's strikes me as, well, strange exposure to alleged mass-temperature relation was not long ago a boring familiarity. Akin to an adult asking where the North Pole is. But hey, that's just my opinion.
