Hello,
The pushes times is on behalf of the total push times of the regional inquiring period, namely those who push out an AD, the system will record it, intermediate contains the statistics of the same account which is pushed multiple times; But the push independent visitor number represents the statistics of the all be pushed users accounts, namely the same account will only be record once though it is pushed several times. So the push independent number of visitors can more reflect the user range of the pushed advertising covered.
Hope to help you!
