I'm not expressing any particular view on the overall topic either way
here, but for the sake of accuracy, I believe that that is not in fact
what the data you collected says. It says that, at the point in time
when the data was collected, 97.2% of those servers were currently using
less than 1.5 GB of /tmp. Temporary files are temporary, and often
bursty; a single point sample might line up with the high-water-mark on
those servers, and it might not. But if you're going to quote
statistics to three significant figures, then people reading it might
reasonably expect more precision in their construction.
