Reality, much more different for me.
I wear modern golf clothing, not bulky stuff. I do yoga for golf before every round I play. I am as loose as I can be. My distance differences in temps between 40 degrees and 80 degrees is huge. Seriously, a 135 yard 7i in winter is good. In season, it is closer to 150 or even more. Dense, cold air has a lot of affect. So does cold, air temp golf balls. So does added clothing, golf designed or otherwise. So does cold wind. Added up, it all hurts those of us who don't have big fire power, probably more so, than those who do. I don't give a shit what has been published. I know my game and I know it affects me much more than has been theorized. And my guess is that BK and other seniors might agree. It ain't necessarily all black and white.
Same reason I don't get too hung up on indoor launch monitor findings. I use them for comparison between various club/shaft options. Not to see how far I actually hit the ball. I have proven over and over again, on the course, that what an indoor launch monitor says and what my actual distance is, measured by rangefinder, on the course, can be drastically different, and I am always longer than the monitor suggests, usually by 10-20 yards. Maybe I just hit the ball better outside, than inside a darkened room with no visual references like I might have outside. Whatever it is, launch monitors never give me what I know from playing over 125 rounds a year, using a rangefinder, what distance I truly hit the ball.
I'm old school. I use technology to help me theorize and make smart decisions around the course. But I believe in seat-of-the-pants feel/see-it-with-my-own-eyes confirmation much more.
