.25 a week is 1 pound of muscle a month for long term lifters, which I previously posted in here.
.5 is possibly doable on the max end for newb gains, which Davis is not.
He gained 5-6 pounds of muscle if we're being generous. I would guess he "supplemented" so bump that number up slightly.
"In one study from the University of Central Missouri, experienced lifters gained an average of 2.18 to 2.33 pounds of muscle over the course of an eight-week training program—not as much as you might expect from a newbie just hitting the gym."
