Kyle,
Yes, short green to tee walks affect speed of play. Its not always under the gca control in housing courses. And, there probably was a strict word limit on the article, which I can attest to writing for the same publication!
For that matter, I can think of a few other things to add (and probably did, as I recall an ASGCA article from years ago that I contributed to)
Specifically, design that encourages golfers to:
1. Exit the back of the green, rather than walk back into play
2. Enter the green from the sides or back if coming off their cart
3. Take the shortest route to next tee
And, no mention of eliminating:
Blindness, so golfers can play as fast as possible,
Short holes where golfers who duff a shot wait to reach the green in two,
Reachable par 5's and driveable par 4's early in the round, etc.,
Sand bunkers front right of green,
Deep rough and native grasses to reduce ball searches
Or adding
Sand bunkers as save bunkers to keep lost balls to a minimum,
using pine straw or light rough for same,
containment mounding, but not so much that cart travel to fw from behind the mounds in uneccessarily long
Add in really looking at individual hole length to reduce shots altogether (such as 320 rather than 280 yard par fours from the forward tees which force even the best women 140 yard hitters to reach a par 4 in three, rather than 2 shots.
