Reading the report it was interesting to notice not only the good call by the positioning engineer to raise his concerns, but also the sound presence of mind, along with the CC, to sit on hands once underway. With the ASDA from B and the V1 in use any prompt to the flightdeck could have lead to an abort and overrun. That said, with the good VMC I'm sure the crew would have made a decision based on the situation ahead of them.
Long live ginger beers.
