+## Overall Average Pass Rate for a Test (Including Retries)

+Query suggested by @dougbu for getting the overall average pass rate for tests, including retries.

+- `ts`: [Kusto timespan format](https://docs.microsoft.com/en-us/azure/data-explorer/kusto/query/scalar-data-types/timespan). How many days ago to query.

+- `repo`: Repository to filter on. Set to empty string to inclue all repositories.
