Letting $P(u,x)$ denote the regularised incomplete gamma function, it is shown that for each $\alpha \geq 0$, $P(x,x+\alpha )$ decreases as $x$ increases on the positive real semi-axis, and $P(x,x+\alpha )$ converges to $1/2$ as $x$ tends to infinity. The statistical significance of these results is explored.
