You might want to do some math and re-examine your biology books related to protein absorption in the intestine. There is indeed a limit to how much protein you can absorb. And believe it or not, Jay can probably only absorb about 50% more than the granny. On a good day.
More than about 250 grams a day is a waste. But don't trust my word, do a Google search and some simple math. Whey is a fast absorbing protein, so hit Google to see how fast whey is absorbed, in grams per hour. There are 24 hours in a day. Do the math.
As for the 35 grams per meal, I explained the rationale in this post:
Protein absorption meal frequency question
In a nutshell, only the first half of your intestine really absorbs protein, and depending on how fast your stomach empties, your meal might not spend enough time in that part of your intestine for all the protein to be absorbed.
Also, more than about a gram per pound of body mass (assuming you're not fat) is a waste. Think about it. If all that protein went to building muscle, and muscle is about 25% protein, then 120 grams of protein would equal a pound of muscle. And I think you'll agree that no one gains a pound of muscle a day.
