By default DPA shows the top 15 waits for a rolling 30 day period. However, for any given the day the total amount of wait is likely to include statements not found in the top 15 statements.
By including a sparkline in the main view we could show to the user the difference. In other words, we could show there was 30 hours of total wait for all statements, but only 20 hours of wait were from the statements included in the top 15.
