The number that would display on the Report Card for the email send statistic is 100. This is because the Report Card shows the total number of prospects that have reached a specific step in the program, regardless of the date range that you filter by. The date range filter only affects the data that is shown in the Engagement History table, which shows the number of prospects that have taken a specific action on a specific date. Therefore, even if the user filters the program to show a date range of Tuesday through Friday of last week, the Report Card will still show that 100 emails were sent on Monday, as that is the total number of prospects that reached the first step of the program
