If it had done this, as far as I can tell, this would have almost been a non-event. I wonder if the panel asked this question ?
The report says they interviewed Frequentis and asked them questions, some of which were answered at the time and some later. The problem with any Interim report is that you never know for any particular aspect whether that's all you are going to get or a full and reasoned discussion will follow in the main report. Given the lack of technical detail from Frequentis in the interim report I'm hopeful that the latter will be the case but we'll have to wait and see.
For me this interim report raises more additional questions than it answers which is incredibly frustrating but par for the course.
