Distance is a major factor for better scores
In general, training for distance is a huge advantage, the top 10 players in driving distance on the PGA tour in 2019 include names such as Rory McIlroy, Dustin Johnson, Brooks Koepka and Justin Thomas. Your main aim should be to train for distance, since 1 mph in clubhead speed leads to 3yds more distance with your driver.
When you have more golf balls in a lake or trees then on the fairway you cannot play a decent round. So the big question is, when do you train for accuracy and when do you train for distance?
With the calculator you can judge when to train for distance or when to train for direction.
