The benefits of protein reach a maximum at 1.8 g/kg/day for strength training and 1.4 g/kg/day for endurance training. I use CRON-O-meter for dietary calculations.

Timing of protein doesn't matter all that much with respect to absorption. Intermittent fasting in which you fast 20 hours and then eat all your calories in a 4-hour window doesn't hurt muscles. When you eat a lot of protein, the intestines slow down so that the percentage absorbed won't decline.
