Also interesting to note that "protein pulsing" is also seen to be more effective than just eating all day long (and intakes are pretty high below).

Background: Adequate protein nutrition could be used to limit gradual body protein loss and improve protein anabolism in the elderly.

Objective: We tested the hypothesis that an uneven protein feeding pattern was more efficient in improving protein anabolism than was an even pattern.

Design: After a controlled period, 15 elderly women (mean age: 68 y) were fed for 14 d either a pulse diet (n = 7), providing 80% of the daily protein intake at 1200, or a spread diet (n = 8), in which the same daily protein intake was spread over 4 meals. Both diets provided 1.7 g protein•kg fat-free mass (FFM)-1•d-1. Protein accretion and daily protein turnover were determined by using the nitrogen balance method and the end product method (ammonia and urea) after an oral dose of [15N]glycine.

Results: Nitrogen balance was more positive with the pulse than with the spread diet (54 ± 7 compared with 27 ± 6 mg N•kg FFM-1•d-1; P < 0.05). Protein turnover rates were also higher with the pulse than with the spread diet (5.58 ± 0.22 compared with 4.98 ± 0.17 g protein•kg FFM-1•d-1; P < 0.05), mainly because of higher protein synthesis in the pulse group (4.48 ± 0.19 g protein•kg FFM-1•d-1) than in the spread group (3.75 ± 0.19 g protein•kg FFM-1•d-1) (P < 0.05).

Conclusion: A protein pulse-feeding pattern was more efficient than was a protein spread-feeding pattern in improving, after 14 d, whole-body protein retention in elderly women.

and actually T-nation has an article about that as well (including reference to the study above):

Hence why many have success with some larger protein meals and IF....as there is much more going on with the body as a whole....rather than always micro-focusing on meal to meal response, whole body up-regulation and increased utilization is important.
