F/O (incorrectly) commenced a go-around.
DW, I respect your experience and I agree with most of what you say. That said, I still firmly believe that the benefit of using all available means of reducing speed should be used. We all accept, I think, that reverse thrust is at it's most useful in washing off speed initially and thus reducing brake energy required.
I disagree with your comment in the final paragraph of your most recent post however. The F/O did not decide to commence the go-around, he responded to the instruction of the Captain to "go-around". As for the Captains "got it", did he really mean "I have control" or was he asking a question of the F/O, which apparently is the way the F/O took it. The reality is that no-one, including the Second Officer, really knew what was going on. The "Front Office" was in a state of confusion. The F/O even stated that he was pulling back on the thrust levers, (against the idle stop as at no time was idle reverse selected).
