The only thing that sticks out is your claim to have an average drive of 197 yards. I don't think it makes any sense to say that would be your average drive like it would be your "typical". When someone asks "How far do you drive?", most people think with a driver.
Yes, I could claim that my average drive distance is 197 yards as well, but the next time I hit into a group at 260 yards away I'll just tell them that some guy on the Internet told me that my average drive is only 197 yards.
And I can say that my average drive is just shy of 200 yards, because sometimes I use my PW off the tee which cuts my 240 yard drive down to 197.
It just doesn't make sense to quote such a number.
I agree it doesn't make much sense but it was the first time I attempted such an experiment and it made sense to me at the time. If I started over I would do it differently. But there are threads here that specifically state average distances (Average Distances... How far do you hit each club? and don't lie...), and people often post citing "average driver distance" numbers ... so?
I do think it is to my point though that most people are not lying. Online users posting "my average drive is XYZ" probably do not really mean average or if they do only some restricted kind of average. In the absence of information about the data and how it is used it is just a number without any context. Given some information about the data and how it was processed, it was easy for you to conclude (rightly) that while 197 might be correct it is hardly useful.
I also agree that the only club anyone ever asked distance for is driver (I alluded to that). I used to say "I'm not sure, what exactly do you mean?" and 100% of the time the answer would be along the lines of "Well you know, on average how far do you hit driver?". I do not take much responsibility to read minds but it is my fault for not leading with better questions like "You mean under normal conditions what is a good drive for me?".
