Though I know a non-regulated flashlight shouldn't have a flat discharge curve, I was still shocked by the SF E2 brightness drop in the first 5 min. as indicated by fuja's graph:

This makes me wonder how does Surefire measure the brightness? In the first minutes? Based on the relative flat portion of the discharge curve? Or some kind of (weighted) average?
