I recently saw a 2017 driver comparison and the thing that stuck out to me was each of their testers had a driver swing speed of 103 to 118 mph. With my girly swing of low 90's the test results mean squat.
Some years back Spaulding found a group of golfers that hit their Top Flight ball further than a Titleist model. Search for the "right group" and you can pretty well prove anything.
Same with Golf Digest 100 Top Clubmaker list. While there are some good ones on it, there are also plenty of bad ones on it. Especially when they name a chain store which would be open about 80 hours a week and depending when you went in there, you will probably never get the same person
