Do not consider people who spend most of time on the range beating balls and who rarely play.
Do not consider players that play very few times a year, scrambles do not count
Do not include children under 13 or miniature golf etc
Do consider climate.
Do not consider the sex, although I think we can assume 85%> are males.
Don't discuss or justify the economy, weather, costs etc etc, we kind of know all that.
So our average golfer in America, I guess we'll include Canada & Europe too
1) how many rounds does your average golfer play per year? Both 9 holes or 18 holes = 1 round.
2) what does he or she typically score ( using their own rules, not playing the ball down for example or tournement rules")
3) what is your average age for your verage Golfer ?
I'll go first
1) 8 rounds
3) 45 years old
