The article you quoted described protein supplementation over only a 13 day period, and described some very strange exercise routines used during the article (3 rep lifts at 70% of 1RM?) Did you read the whole article or only the abstract?
1, Those are way old - the new studies I provided clearly shows a new and improved result.
2, I would take everything regarding cost supplements on bodybuilding sites with a grain of salt as most of those are linked to some kind of producer/reseller of such products. Hence the old studies that show more proteins are good - spikes their business.
3. That is but one study, I linked to many with different routines.
4. I think it's important to pint out to whomever might be reading this that an excessive intake of proteins could actually harm your body. (Int J Sport Nutr Exerc Metab. 2006 Apr;16(2):129-52. A review of issues of dietary protein intake in humans) The theoretic toxic level starts at 3.5g/kg.

The studies I've read have indicated that if you keep caloric excess at about 500, the majority of gains during high protein bulking phases will be muscle, with some water. This is almost exactly what I've experienced.
Again, how did you come to that conclusion?
Did you use a caliper to messure or is it more of an "eye messure"?
It's a MYTH. If you would like to believe it is, go ahead. If you're bulking you WILL gain fat and muscle, thats just the way it is.
The only possible way I know of to gain while trimming down ones BF%, which is far from a optimal situation would be to go by a week-to-week basis. Bulk and exercise for 3-4 days, diet and do cardio for 3-4.
Repeat.
Please consider this as well. Claiming all your excessive intake would build muscle is nothing but a false assumption.

In most situations involving a significant change in body weight, both fat-free body mass (FFM) and body fat participate, but the relative contribution of FFM and fat to the total weight change is influenced by the initial body fat content. Overfeeding: In thin people, the weight gain comprises 60-70% lean tissues, whereas in the obese it is 30-40%.

IIRC 18 of the amino acids can oxidate to glucose. Hence my statement.
