Average added, but take it going forward for what it is, just an average of a short sample.
OKW has the most history 16 years about a 1/3 of the 50 year contract data, SSR has the least 3 years or a little more than 1/20 of the 50 year contract data.
If I were going to use this going forward, I would estimate higher than these averages just to be conservative.
