How is Even Distribution calculated?
Even distribution allows your team to receive a constant flow of data throughout your desired recurrence. When it’s enabled, Pendo will automatically assign each user (uniformly, randomly, and distributed by visitorID) a 14-day window during which they can see a guide.
Example Scenario
How many users will see the NPS Guide with the following settings:
- Even distribution enabled
- Recurrence set to every 90 days
- Currently have 10,000 eligible users and 100% of them log in every single day
Once Even Distribution is enabled for your NPS survey, Pendo will assign each visitor randomly to a 14-day window when the user can see it. On the first day of your 90-day recurrence period, approximately 15.5% of your targeted segment will be eligible to see the guide. Then, approximately 1.1% users of the segment becomes eligible each subsequent day.
Based on an example of 10,000 eligible users using a 90-day recurrence, this means you expect to see around 1,550 visitors on the first day. The whole 15.5% will become eligible at once on the first day, producing a noticeable bump, especially if your target segment contains highly engaged users. Then around 110 users will be eligible each day through Day 90 so over time you should see smooth presentation.
Can I enable Even Distribution later?
Yes, you can enable this at any time in the schedule section when editing your existing survey. If you already published your NPS guide, Pendo will recalculate in the background to help smooth out users who haven’t seen your survey yet.
