7.3 Detailed methodology steps to calculate <strong>cost</strong>s<br />
The detailed methodology used in order to come up with the <strong>cost</strong> per core <strong>and</strong> the <strong>cost</strong> per core hour is <br />
presented in the following table. In the same time the average <strong>and</strong> median values of the total e-‐FISCAL sample are <br />
shown in the last to columns in order to enhance the comprehensiveness of the way the model works. <br />
