Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The only way to represent the whole price structure exactly is to give all the raw data. If you are allowed to give only two numbers, the best way to characterize it is IMO the one I outlined above. But there are various almost-best alternatives, and if all you're interested in is evolution over time, it doesn't matter too much which one you choose as long as you're consistent. Meaning, IWR's critique has no merit.
