  1. Sincere Question – WHY ALL THE COMPLICATGED TRIANGULATION and calculations, to see what is GOING TO happen. Why not equip the court with 4 high res, high frame rate camera, looking straight down the court and recording – and replaying the ball in slow mo when needed??! I mean we have those cameras now, you can literally see bullets in slow mo…. Would be 100% accurate, and cause less controversy. I saw one tennis match, when in replay of actual video you could see balls were way out, but hawk-eye kept saying those balls were in. I guess it was not calibrated correctly that day…..

  2. 0:23 – Other way around mate. Hawk-Eye in cricket shows what would have happened if the batter was not standing in front of the stumps. Hawk-Eye in tennis shows where the ball just landed.
