Your system is indicating that the Train from Chatswood to Macquarie Park can be done via a MyMulti1 whereas I believe Transport NSW indicates you need a MyMulti2. I called them and yes indeed, Chatswood to Macquarie Park is two zones and thus a MyMulti2, not a MyMulti1, so Opal is cheaper by $0.93 per week.
