I've had the pleasure of working with a personal trainer who has a broad educational training background. She emphasized that creatine "kind of helped" but it was really only that last mile 5% benefit. And the effect would mostly be long-term (1-2 years of dedicated training). She just told me to focus on trying to get 1 gram of high quality protein daily for pound of body weight.
This study is just one study, but to me just highlights her same observation even more.
