I like all the improvements. Just one question: is there a certain reason why the 'reference date' and 'expected publication' is not set after the latest possible date of evidence in this question (2040/01/01 00:00:00)? Regards, Günther.

Since this is a "Timing" question (just disguised as an Ordered Answer Scale question type) it actually does not matter much. Both dates could actually be best set to the end of 2016 to ensure a prompt check for a possible first answer elimination. For consistency and good order, I will do this.

Good idea.
