SQL Server 2008 R2 service packs Are the SQL Server service packs 'cumulative' or 'incremental'?

The scenario is that we have a couple of instances running on SQL Server 2008 R2 RTM and we have been asked to patch it up to SP3 level. I'm not sure if I just apply SP3 or do I need to do SP1 - SP2 - SP3
SQL Server 2008 R2 service packs are cumulative and can be used to
  upgrade all releases of SQL Server 2008 R2 to Service Pack 3.

Given the documentation, you should be able to go directly from SP0 to SP3.
