This is always going to be the same, just over 4.2 joules. The amount of calories you used was less after excreting the excess, but the calorie measurement remains constant.
As far as measuring how much you need I intend on starting a month long process in October where I try various amounts of protein intake and then I measure the amount I am excreting in my urine and study the trend and compare to established norms. I have access to a lab so I look forward to seeing if a diminishing return will the present in the data.
