What Weightings Do You Give Various Distance Influences?

As we wait on the governing bodies to tell us how distances have spiked on pro tours and therefore require even more extensive study, the common response on social media usually obsesses with cause, not effect.

So while we wait on the reports, I've taken Alan Shipnuck up on a fun exercise he suggested in this week's Golf.com mailbag: break down the forces you most attribute to the distance spikes that we've been told have not happened. 

Here's the question and answer from Alan:

Regarding bifurcation, what general weightings would you give the following factors for increased distance off the tee: agronomy, athleticism, technique, ball, club (head and shaft as one), other. -Ryan (@RW_Mountain)

This is an interesting thought exercise. My highly unscientific answer:
Agronomy: 5%
Technique/Trackman: 20%
Athleticism/Training: 20%
Club: 25%
Ball: 30%

My highly unscientific answer:

Agronomy: 0%
Technique/Trackman: 35%
Athleticism/Training: 10%
Clubs: 35%
Ball: 20%

As wonderful as modern agronomy is--really amazing these days and not appreciated enough--it has little impact on elite-playerdistance gains compared to what has made carry distances explode. Healthy, denser turf offsets modern lower mowing heights. Distance has spiked with tee shots and iron play equally. Iron shots to greens are not running long distances off the tee. 

Technique/Trackman: This gets 30% thanks to a combination of more informed instruction, common sense use of launch monitors, and the ball-striking confidence resulting from these forces. More players are learning speed first, fundamentals second and visual appeal a distant third as video is replaced by Trackman.

Athleticism/training: I can't go higher than 10% when I see guys on the PGA Tour Champions averaging longer distances in their 50s than their 30s.

Clubs: The consistency of manufacturing quality, super-lightweight materials, driver head size, the relentless innovation on many fronts and a generation of players reared on better clubs has led to incredible clubhead speeds. 

Ball: Shifting from balatas to today's longer, lower-spin ball has made a profound difference. The improved quality of manufacturing also has further reduced inconsistencies and increased player confidence in the ball. But this number has also lost percentage to Technique/Trackman and club fitting/technology the last few years.
