I think it's safe to say that (sorry to switch up the units) 1g per pound is a good place to be. Not too much not too little. Most data that I've seen has recommended for athletes in regards to performance, gaining and or preserving lean mass is 1.3 - 1.8g/kg sometimes pushed to 2.0 during times of extreme training.
Some of the studies even say as low .8 or 15% daily intake
One thing to note here is the prevalent nature of high carb intake with most of these athletes. Elite athletes and their coaches place carbs above all else from what I've seen.
