I have grown up in Vancouver BC playing the last 20yrs pretty reg @ sea level. I have a 118mp swing speed and 177 ball with 3400rpm..my buddy who plays the last 10yrs in desert golf (Palm and Phoenix area) has a very similar speed test as I do. We recently played and I was out driving him by 10-50yds on average and he couldn't understand why. We are both close in size ( I may have 20lbs on him) but height almost bang on. I say it is because I play heavier sea air @ sea level and therefore have a more driving swing which when in desert climate will just fly a mile. He thinks it has to do with my larger chest area which somehow makes it fly more. Can climate you play reg affect your ball flight or is the science accurate and it does come down to body size for the extra distance.
Could be you have a more "driving" ball flight, but that's not really due to the sea air, just a difference between you guys, you might have the same swing speed but are better fit for the correct lofted driver than he is.
Speed (of the ball), launch angle, spin. Period. For every speed there is an ideal launch and spin combination that maxes out distance.
A 30 yard average gap in your distance is absolutely massive, and my guess is that most of the gap is because you swing it at considerably different speeds. Because while there might be something to the idea that learning to play in certain conditions makes your swing do certain things that for whatever reason make your launch conditions overall more optimal in a neutral environment, it sure doesn't account for 30 yards outside of some super extreme cases.
i guess it could be playing in vancouver (esp. in the winter) that you work towards a higher launch angle and less spin as you get very little roll. and he's used to big roll. altho i actually find with even very wet vancouver u still get decent roll from low drive. always a plug mark with high driver
my range on golftown simulators is 10-12 mph, if not 15 mph (90 to 105) then nevada bob's is different from golftown average (100 mph)nevada bobs claims it's the military uses for precision in measuring projectile speed. seems highly implausible to me altho it does give tight reading i found
