But... that's the way averages work. It's all in the sampling. I see the point you are trying to make, but I'm not convinced it's correct. You are saying the sample size or the location, or the time, they chose for the average wasn't large enough to account for bias. Either that, or you are saying that the majority of golfers play golf at some time or location not accesible by the study. Either way, I think the onus is on you to prove the sampling is faulty. Maybe it is. I don't have access to that data. I'd be willing to bet money that the difference between truth and the representative sample in that study isn't going to make the average clubhead speed go from 85 to 95 or whatever you think it is. Regardless, no one should be satisfied with a 200 yard drive. That's why people want to improve. They know they can hit it 240 or higher if they just work at it.
True. Don't feel bad about a 200 yard drive, but keep getting better and working at it.
