Are these wp-content permissions safe?

As per the following from http://codex.wordpress.org/Hardening_WordPress#File_Permissions

/wp-content/

User-supplied content: intended to be completely writable by all users (owner/user, group, and public).

Within /wp-content/ you will find:

/wp-content/themes/

Theme files. If you want to use the built-in theme editor, all files need to be group writable. If you do not want to use the built-in theme editor, all files can be writable only by your user account.

/wp-content/plugins/

Plugin files: all files should be writable only by your user account.

my permissions should be perfectly fine.
