Ensure that all disciplines are covered in the journal selection.
Your list of 68 journals is inadequate because it does not include any journals for some disciplines. For example, my discipline is not represented in the journal choices. Does the panel believe that no high quality research could possibly come from my discipline? Should institutions be penalized for allowing my discipline to be studied? (My discipline is green chemistry and the relevant journals are: Green Chemistry, ChemSusChem, ACS Sustainable Chemistry, Environmental Science and Technology, Energy & Environmental Science, etc.
As mentioned earlier Environmental Science & Technology is a must, as is Geophysical Research Letters.
