BV is high and that is all but doens't mean anything because the test given to measure BV is protein only at a given amount. . There is a reason why digestive enzymes are included with many Whey supplements.
If you are talking about in between meals then your logic if even more flawed because you don't need a fast absorbing protein in between meals. You want a long sustaining protein that keeps a positive and sustained nitrogen balance, not spikes. That is why egg is so good becasue the NPU score measure retension of food nitrogen consumed and it a better indiciator on how the body utlilized protein rather than just the measure of how much is absorbed (as in BV). Also BV shows how much is absorbed but if you do not utilize those amino's they eventually get deaminated and excreted (because of excess buildup of aminos due to fast absortion in a normal feeding state). The physiology of post wokrout and normal feeding times are not the same and you need to realize this.
As for digestion, its faster and that is it. It doesn't get absorbed better at all (especially during normal feeding patterns) and the NPU already shows egg to be superior in overall utilization of protein because of a slower extended release of amino's.
"The highest PDCAAS value that any protein can achieve is 1.0. This score means that after digestion of the food protein, it provides per unit of protein, 100% or more of the indispensable amino acids required by the two- to five-year old child. A score above 1.0 is rounded down to 1.0. Any amino acids in excess of those required to build and repair tissue would not be used for protein synthesis, but would be catabolized and eliminated from the body or stored as fat."
