NBCC 2010 Snow distributions for simple arch roofs Figure G-2

NBCC 2010 Snow distributions for simple arch roofs Figure G-2

(OP)
Hi there,

I was recently trying to determine the snow load distribution on an arch roof. There are 3 cases to consider. Case 2 and 3 have a footnote which states "use case 2 or 3, whichever produces the LOWER total load per unit length of building perpendicular to the span". I understand that the case that produces the highest peak does not necessarily produces the highest load on the span because it's dependent on the curvature of the distributions. However, I'm having a difficult time understand why they say to use the LOWEST load.

Any thoughts or explanations for this?
