I am of the opinion that what ever speed a golfer plays at, is going to be the same speed they do everything else in their life.
Different folks move at different speeds, which i relate to a person's individual genetics. It's their own timing factor, or comfort zone if you will.
The responses still would have been the same. Close to 100% would take the best drive over the best putt without question. There are numerous studies in strokes gained to prove the point including @iacas's book "Lowest Score Wins".
If one is at the first tee on time, who cares how much time they spend in the parking lot?
FWIW, I like to arrive around 45-60 mins. Early so I can warm up and stretch. But that’s just me. I play with several people who are drive up load the cart and go to the 1st tee guys. None of them play slow.
Merry Christmas and Happy Holidays all. 🙂
I know it’s a poor question. I even admitted that last night. I think the question would have been better if I said the best driving, and left out iron play altogether, implying that your iron play in both scenarios is neither good nor bad, just okay.
