PUT YOUR READINGS IN CONTEXT

Compare controller snapshots

Keep a record before changing a setting or connection, then compare the observations under matching conditions.

Compare your saved test snapshots

Save snapshots from the tester on this browser, then choose two below. Nothing is uploaded.

Compare like-for-like conditions. Different browser mappings, firmware, profiles and connections can change the values. A lower number is not a complete measure of controller quality.

Open the tester to save a snapshot →

Make a useful comparison

  1. Open the tester, check your controller and run the resting-stick measurement.
  2. Add a setup note such as “USB, default profile” and save a snapshot.
  3. Repeat after changing one thing, then save a second snapshot.
  4. Choose the two records above. Check their names, mapping and notes before interpreting a difference.

Snapshots stay in this browser’s local storage. They are not synced between devices or domains. Clearing browser storage removes them; download a JSON report if you need a separate copy.
