It annoyed me that whatever I did, the game seemed to know exactly how to counter it. Finally I discovered that each time, you need to leave a gap of 1 hour 15 minutes because that is the lowest number that you and the computer can do in 2 moves. The times you want to end up on are 7:00, 8:15, 9:30, 10:45 and finally 11:45. Each of these moves are 15 minutes apart.
