The 'Initial Stats' is a setting in the optimization dashboard that allows you to set the start date from which adCore will consider your statistics. Anything before this date will not be considered when adCore takes action in your account.
This is a great feature to use if you want adCore to disregard irrelevant data.
Click on the schedule icon to set the 'initial stats' date in the following format and enter it in the appropriate place (yyyy-mm-dd)
If the Initial Stats field is left blank, the Optimization tools will track data from the campaign's creation date.
