Partitioning and formatting are independent. The partitioning scheme specifies how the disk is divided into one or more volumes. The format of a volume (each volume can be formatted in a different way) specifies how the files of a volume are stored in the space reserved for the volume by the partitioning scheme.

Disk:Partition Scheme ratio is always 1:1.

Partition:Volume ratio is always 1:1.

For bootable SD! backups, you should use the proper partition scheme for your hardware (GPT for Intel, APM for PPC). And since SD! only works with HFS+ volumes, that is the format (filesystem) you will need to use. Both the partitioning scheme and the format need to be correct for a bootable backup.
