For example, a market settling at Friday, October 23rd 11:59pm Eastern Standard time, would include in it's calculation of it's average the 7-day period of October 17th to October 23rd.
If the reporting of data by Etherscan is postponed for more than 48 hours from its original schedule time, all bets on the event will be void/"no action" and the stake returned to your account. The calculation of the average happens the moment the 7th data period has been reported. Any data revisions after that moment will not revise this average, but any revisions before that moment will.
