Hi!

I have a series with two paths that take users to different checklists depending on their experience level. I wanted to review each checklist’s performance to see if our recent changes improved completion rates.

If I check the Series Performance Summary Report (checklists section), I get:

• Total sent (The total number of checklists that have been sent and displayed to users within this Series.): 61,734
• Completion rate (The percentage of checklists sent within this Series where the recipient completed the whole checklist.): 23.5% from previous 55 days (14,528 unique completions)

If I check the checklist individually, I get these numbers: 

• Checklist 1:
  • Total sent: 16,021
  • Completion rate: 4.93%
• Checklist 2:
  • Total sent: 4,437
  • Completion rate: 2.84%

The amount of checklists sent are very different (from 61k to 20k if I add the individual numbers), and the individual percentages of completion are low and become way higher if considering both.

Which data should I rely on to measure the impact of our changes? I’m not sure how to interpret the difference.

Thanks in advance!
