Examples

For a discount-rate flag with variants 0%, 20%, and 30%, impressions are logged when users see the applied discount, and events are tracked when they complete a purchase.

​
Average or Sum Purchase Price

Let’s explore how an average or sum metric tracks purchase value for the discount-rate flag, testing which variant drives higher spending:
1

Set It Up

Select purchase_event and enter price as the value field to aggregate:
  • Events auto-populate from client.track().
  • Property Events let you derive multiple metrics from one purchase_event.

Interpret Experiment Results

See a simulated FlagSync dashboard for the discount-rate experiment, testing how discount variants impact average purchase value:

  • Trend: The chart shows 30% (pink) leading at $147 average purchase value, followed by 20% (orange) at $108, with 0% (blue) at $83.
The 30% variant is the clear winner, increasing average purchase value by 76.4% over the baseline.
