I found this article via John Abela’s facebook link. It’s definitely worth a read and has some meaningful calculations to help compare quilts. For instance:
-Normalized down fill for 800,850,900
-Fillweight (normalized):quilt area
-Down saturation, ie ‘overstuff’
-Volume and other measurements of popular quilts
-“Standardized” roughly to 20* for each quilt
Definitely some time was put into making the calculations and explaining them.
