That was a very thorough report. Although the crew thought that the runway was dry they had set the numbers for a wet runway, they were still good even at the intersection.
A lot of factors should have led to a "go" decision. Rather than dwell on how the captain screwed up (or didn't, if that's what you prefer) we should take this report and reflect ourselves how we would handle this situation. Reports are there to learn lessons from, not place blame.
