Am I missing something or is the Venn Diagram horrible. There are "Stage 1 Compliant" and "Stage 2 Compliant" areas, the overlap of which would logically be "Stage 1 and Stage 2 Compliant" Instead there is a third area for "Stage 1 and Stage 2 Compliant" with the count in the label instead of the area. That whole chart is either ridiculous or I am a moron and can't parse it with my brain.
