In terms of the successfulness in this discussion I would give them a 3 in a 1-5 scale. This is because they had a lot of awkward silences. 1 of the moderators did not seem to be talking and leading the discussion at all. My advice for next time would be to have your moderators leading the discussion. The best moment in your discussion was around 8 minutes. This was when the conversation was most in depth and well progressing.
