Can Each Mixpanel Feature Flag Have Only One Experiment Report, and Can Report-Level Corrections Be Made?

Sharon L. · 2026-08-07T15:24:10.128Z

Each Mixpanel Feature Flag can only have one connected experiment report? What if I set something wrong, could I make report-level correction retrospectively or the whole report would stay contaminated all the time?

Feature Flag & Experiment Report Connection
One Flag, One Experiment?
The knowledge sources don't explicitly state whether a single Mixpanel Feature Flag can be connected to only one experiment report at a time. I can't confirm or deny this with certainty based on the available documentation.
Retrospective Corrections to an Experiment Report
The good news is that Mixpanel does allow you to change experiment settings mid-run, with some important caveats:
"Mixpanel analyzes your experiment on the fly, so you can adjust settings at any time if needed. If you notice a configuration mistake — like selecting Frequentist when you meant Sequential — feel free to correct it, even if the experiment has been running for weeks." [Changing Settings Mid-Experiment]
So for genuine configuration mistakes, you can fix them retroactively without the report being permanently "contaminated."
What You Should NOT Do
The key warning is around p-hacking — don't adjust settings because you don't like the current results:
"The one thing to avoid is changing settings because the current results aren't what you hoped for. If you adjust the confidence level, metrics, or duration in search of a significant result, you're more likely to find something that looks meaningful but is actually noise." [Changing Settings Mid-Experiment]

When to Start Fresh
If you want to test a fundamentally different configuration rather than correct a mistake, the recommended approach is to restart the experiment:
"If you want to test a different configuration, restart the experiment instead. This resets the data and ensures your analysis starts fresh." [Changing Settings Mid-Experiment]

In summary: Genuine mistakes can be corrected on the fly. The report won't be permanently contaminated as long as you're fixing real errors rather than chasing favorable results. For deeper reconfigurations, restarting is the clean path forward.
