+two valid values: `subtest` and `interop`. `subtest` will represent the current
+view that exists on wpt.fyi and will be enabled by default. `interop` will
+display a view that more closely mirrors the Interop-20** scores.
 
 **Note**: In the interest of avoiding scored comparisons being visible outside
 the tests that have been agreed upon for Interop-20**, this `interop` view will
 only be available when viewing tests with an `Interop-20**` test label. The
 `interop` view will not function outside of results without this label.
 
 ## Risks
-* This change will cause a net loss in the percentage of passing
-tests/subtests, as the harness status passing has been artificially inflating
-some subtest numbers.
-* This change will require a rework of the current process for aggregating and
-summarizing test results, so older test runs will still be aggregated with the
-harness status and display inflated passing percentages.
