CR is usually pretty accurate. However, I have a friend who is a strength coach and is curranly and had worked for NFL and NHL teams. The guys knows his stuff. I use AES and asked him about the study. He said there where several componants of the study that were flawed. To be honest I don't remember all the technical stuff he went in to but I did get that as long as you go witha good, reputable company you are good to go.
