When the tables/graphs below are used together they show that when the parts are run at their higher power ratings, the parts will run hotter, which has the potential of causing the resistance of the parts to shift more over the life of the part.

If the same resistor was instead run at 1/4 W in a 70 C environment, the element will heat up to about 30 C over ambient, and over the life of the part the resistance value could shift roughly 0.5 %. And if the resistor was run at it maximum power rating of 1/2 W in a 70 C environment, it will heat up to about 58 C over ambient, and you could see the resistance value shift roughly 1 % over the life of the part.
