Whew, that's about 180 degrees opposite of my little anecdote, not that my anecdote has any direct bearing. The information my customer was asking was difficult to obtain and I was seeking help to unearth it, in I suppose a spirit of "the customer is always right", only to have my perspective turned around to what was an equally important question.
I don't expect further and further layers of information about Buxton to be damning, merely quantities of conflicting and uncertain medical data, coming back to "well, this might work, or it might not," from professionals with considerable experience in such matters. Medicine is not an exact science.
