 Description   

The expected failover window stated in the documentation is 10-20 seconds, during which writes will not be expected. However, it appears that this figure may be outdated due to the enhancements to the replication protocol released in 3.2. The release notes (https://docs.mongodb.com/manual/release-notes/3.2/#replication-election-enhancements) say that the failover time is reduced, but don't mention by how much.

Is the 10-20 second window still applicable?

The default election timeout in pv1 is 10 seconds, so I think saying 10-20 seconds still seems reasonable. People who have changed their election timeout in order to achieve faster failover will already know what to expect.
