I realize the value I quote is specific to the MIT environment studied, but I'd rather not complicate things. It gets the point across, and the URL is given for those who want to investigate further.

(Not that I expect much credit for this simple approach. But now I have something I can put in my bag, ready for the next opportunity.)
EDIT: Also, the term "use" might be considered vague or otherwise non-specific. But it is brief and fits the intended tone of KISS (Keep It Simple Stupid). In my mind, "use" doesn't create the mental 'stutter' that "consume" or another verb might. And perhaps its repetition in the second sentence provides a subliminal reinforcement. (While the use of "do" avoids repetition within the same sentence to negative effect. Call the literary criticism police; I'm out of control.)
