The following tables represent a compilation of multiple research studies that published results of cook loss or
cook yields in peer-reviewed journals. The results are separated mostly by primals and subprimals where
space allowed. All of the data are backed with references which can be found at the end of the document and
cross-referenced throughout the document. For clarification purposes, a legend of sorts is at the end of the
document to assist with interpretation. Because the treatment factors used vary greatly from study to study, an
“average” of the numbers for each muscle would not be accurate; thus there is not a single number, or average
of the data gathered, in the document.
