You are asking people to predict future based on incomplete information - even after Imetelstat data presentation at ASH it would still be incomplete information - even people with same or similar background would predict differently because everyone has to use some other information in the background to make this prediction, and that background information are different no matter what they do.
There is really no dispute what the abstract said, it can't be any more clear. To me, it is quite consistent with ET data, nothing far beyond that besides indication, plus it shows MF is a tougher indication than ET. As of CEO's answers, his answers would be different depending how you ask him the question. If you asked him improvement of symptoms, of course his answer would be yes because abstract showed there were some symptoms improvement. If you asked him improvement of ALL symptoms, I am quite sure he would not give you definite yes answer because abstract didn't show that at all. So, most people would interpret his response based on their own bias/inclination. Prediction about future event can only be verified after future events actually happen.
