Have people read the other nutty part of the 20/40 rule change, I'll just paste it off the NRL site.
Quote: "The 20/40 kick will work in a similar fashion to the existing 40/20 rule.
A team in possession will earn another set via a tap-kick if they kick the ball from within their own 20-metre zone and find touch within the opposing team's 40-metre line.
Under the change to the scrum rule, the team feeding the ball will have the option of setting the scrum at three locations – 10 metres or 20 metres from the sideline or in the centre of the field, in alignment with the black dot on the crossbar.
Teams will be given five seconds to inform the referee of their choice of scrum position.'"
