I've had many claims kicked out because of the Olympic average calculation. I believe there is a recommendation from one of the groups that we move to the better of a simple average and an Olympic average. If you think of a ten-year cycle for typical commodity prices, the seven-year average better reflects the ten-year cycle than a five-year average, which basically cuts it in half. If you're at the end of a bad cycle, then you're at the mercy of your reference margins. So seven would better reflect the ten-year cycle for commodity prices.
