A new trace flag, 2371, was introduced in SQL Server 2008R2 SP1 to lower this threshold. Imagine a table with 10 million rows; over 2 million rows would need to change before statistics would be marked as out of date.

This means that in SQL Server 2016, you only need to use trace flag 2371 to get that lower threshold if you have the database compatibility mode set to 120 or lower.
