Conclusion:

There aren't a huge amount of unsolds at 9.5, mostly due to 10 recently being the high end and many traders are still waiting at that price. However, the unsolds at 9.5 have been sitting on them for a very long time. There are just way too many sitting in the market at 9 keys to make 9.5 viable to include in the range anymore.
