Ski boot stiffness index

How does the ski boot stiffness index get determined, and how does it vary between manufacturers? I usually see stiffness indexes between 50 and 150, and I wonder if some manufacturers inflate them, or if there even is anything like a standard. I have Head Edge 9.5 boots that are labeled with 5.0/6.0 (adjustable) stiffness index ... are they 50/60, or is Head's own weird system? How do you navigate the whole mess of marketing?
