I spoke to the pilot flying the Tobago at Launy. He said that he had the Virgin aircraft sited at all relevant times and there was never ever any chance of a collision.
Dick, as people keep trying to tell you: the Tobago pilot thought that 2 degrees at 15nm would be fine. He clearly misjudged the path of the 737, believing it to be turning when it wasn't. He triggered an RA, and passed within 200'/1nm (even after the other aircraft complied with the RA). His assessment of the collision risk, or the acceptable miss distance, is quite clearly worthless, and I'm surprised you keep coming back to it.
