If you actually look for studies on protein absorption amounts, there are none that show that we can't absorb more than 20 g at a time. It's a question that keeps coming up, but the researchers can't pin it down for sure.
I don't worry about 30 g per meal being too much - but, just in the interests of keeping a steady flow of protein, I do try to get between 20 and 30 grams 3-4 times per day.
I originally had a nut that told me that I wouldn't be able to absorb more than 60 g per day anyway, so don't bother going higher. I researched, took her documentation, and she changed her tune and started really researching us. Unfortunately, she got so good she was hired away by a practice closer to her home that paid better.
Nuts learn what they have been trained in, and many don't have the time to research our weird anatomy, even if they work with bariatric patients. I know the nuts assigned to my surgeon's office (it's a large hospital group, he doesn't get to hire his own) routinely tell post-ops to get 50% of their daily calories from whole grains, with veggies coming next and protein last. So far they're not real amenable to looking at the ASMBS guidelines, so I don't see any of them.
So that's a long way of saying, if you can do 30 g 2x daily, go for it. If you can do 20 g 3x daily, go for that. See how much protein YOUR body wants - we're all a bit individual, mine wants 125-150 g per day, so 60 g is the minimum you are working towards.
