To be fair though, it's been pointed out that Dan is probably closer to a 12 than single digits in reality. Either way, I think you see those kinds of anomalous long balls less and less as your swing gets better. I can still crank iron shots 15 yards extra or so if I wanted to but it's because I swing a lot differently and deloft the club, not because I create a vortex with my swing in which the laws of physics are suspended. I don't think I've flown my yardages by much in a while actually, so I chalk that up to improvement. Consistency is one of the best things to have in golf.
As for the swing speed radars, I haven't told this to anyone before, but I remember an experience I had with it the last day I had it. I could always get into the high 100s and low 110s with driver, but after I improved a bit I was getting into the 115-120 range, my correct driver speed. Predictably, one day I was trying to increase it more and I got several readings including 124, 128, 130, and 131. My swing was getting more Bubbaesque and I was basically jumping and doing crazy things to try to get a high score. That same day, by perhaps a slight coincidence, I missed the ball so badly that I hit the unit 3-4 inches away and broke the LCD screen. That was a poignant moment for me in my golf career. I wondered how I'd missed the ball so badly, then I realized I wasn't focusing on the ball really.
It's embarrassing but true. I spent all last year hitting at targets and focusing on my ballflight and I now hit more pure shots per bucket than I think I did the entire time I practiced with the radar. And I might have had plenty of swing speed to have a 300 yard drive 2 years ago but I didn't actually get one until last year when I had 2 in one round. I wish I had spent that 100$ on something else.
And I don't believe the thing was terribly accurate; it would generally work OK and I believe the consistent readings I was getting are correct, but there were plenty of high and low errors. I also got 114 with a 4 iron, which is a bit high I think. So trust Trackman but don't worry about the SS units unless you're willing to completely lose focus on your game. I didn't break 100 until after I got rid of the damn thing personally. I'd considered replacing it but it's a waste of money at this point because my clubhead speed is fine where it is.
