If you look at the Super situations summary page prior to the 8:45 am update, you will not see all the situations for the day. Some situations are dependent on the prior night's results. Therefore they won't appear before the morning update is run. The afternoon update will rerun the situations based on line moves. It's possible that some situations will appear or drop off at that time depending on the line changes. However, there will be far fewer changes on this update than in the morning update.
