No, sir, we have not seen any paper that actually lays out their methodology and assumptions. Again, differences in assumptions can mean very different rates in these costing numbers. We highlighted with great effort in our paper the list of assumptions we're making.
For example, assuming static status--for instance, the continuation of current occupancy ratios in prisons when we do our costing, or no behavioural impacts with respect to other aspects of the system--can have a big impact on the ranges of cost. But we have not seen that type of information.
