Default LIGO Conspirators Know No Limits

http://blogs.discovermagazine.com/d-...ve-detections/
" But LIGO heard another suspect gravitational wave signal that got less attention. Though it wasn't as strong, it looked promising. An analysis of that event, labeled LVT151012, has shown with 90 percent certainty that it also came from a pair of colliding black holes. That's not sufficient for scientists to deem it a "detection," but the LIGO team is confident enough that they're using it to start piecing together a picture of black holes in the universe. "The best guess we have is that binary black holes merge in our universe at the rate of a few per hour," says LIGO scientist Jolien Creighton of the University of Wisconsin-Milwaukee. Assuming LIGO's early data are not exceptional, scientists will soon piece together the first black hole census. Extrapolating from those two mergers in 16 days to the larger universe beyond what LIGO can see, the team calculates that a few binary black holes should merge every hour in the cosmos. "It does imply that we should have tens of detections over the next few years, and hundreds through the end of the decade," says Hanna. "That's enough to do some pretty significant astronomy. That's a big population." Based on the signals seen so far and the sensitivity of LIGO's detectors, scientists estimate that they'll see between 10 and 100 black hole mergers during the instrument's next observing run, which begins in late summer. "When the second science run turns on, we'll be seeing more systems at rates of once every few days or weeks," Creighton adds. "And the run will also last longer, so we will be collecting more and more events." "

"At rates of once every few days or weeks" but that begins in late summer? Not now? Even though the signal they have already "discovered" was "a whopping big signal"?

"People are hugely excited. The rumour is that it's a whopping big signal, in other words, it's unambiguous, and that is fantastic," said Pedro Ferreira, professor of astrophysics at Oxford University, and author of the 2014 book, The Perfect Theory: a century of geniuses and the battle over general relativity."

Here LIGO conspirators are even more outrageous:

http://phys.org/news/2016-04-ligo-ba...e-gravity.html
"Prior to the landmark experiments that led to the detection of gravitational waves, researchers believed that there was likely a very nearly constant stream of background gravitational noise moving through the cosmos, generated by black holes and neutron stars merging, but had lacked any physical data that might allow them to estimate how much background noise might exist. With the detection of the gravitational waves that resulted from the merger of two binary black holes, the researchers suddenly found themselves with actual concrete data, which they have now used as a basis for calculating the likely amount of gravitational wave noise constantly bombarding our planet. To make predictions based on data from just one event, the team started with the assumption that the event that was measured was not one that was out of the ordinary... (...) Doing so, the team reports, indicated that there are likely 20 times as many black hole binaries out there as has been estimated, which suggests that there is likely 10 times as much gravitational noise than has been suspected. The team acknowledges that because their results are based on a data from just one event, their conclusions could be wrong, but, if they are right, they note, they should be able to detect them within just the next five years or so as the LIGO and Virgo detectors grow to full strength."

Why should "whopping big signals" be regarded as noise whose detection will be postponed for five years? If black hole binaries are so frequent, isn't it logical to have, without any delay, multiple detections like the one that allegedly occurred on 14 September 2015?
