15-Inch Cups Cut 45 Minutes Off Rounds?

Larry Olmsted summarizes the most salient points from Monday's HackGolf/TaylorMade event with Sergio Garcia and Justin Rose where the two were summed to promote 15-inch cups, 9-hole rounds and outside the box ideas...at the six-course, name brand architect driven Ritz Carlton Reynold's Plantation.

This was fascinating:

Two weeks ago HackGolf debuted the new oversized holes for the first time at Southern California’s Pauma Valley Country Club, ands says that the new cups reduced the length of an 18-hole round from 4:30 to 3:45, while many golfers saw a 10-stroke improvement in scores.

I've putted to a big cup before and it's certainly a lot easier. In terms of skill, it's not much of test nor nearly as interesting. However, since no one seems to want to turn the clock back on slow greens, our silly, wasteful addiction will apparently go unabated.

So perhaps 15-inch cups have merit as a way to offset the pace impact of faster greens?

Thoughts?
