Concur! Have seen all inexperienced staffs, and many experienced ones, die on the CG-CC-CR-CV hill early in mission analysis.

Unfortunately, it is a vulnerability's special relationship to the CG that makes it a CRITICAL vulnerability, rather than just a run-of-the-mill or trivial vulnerability. So can't completely dismiss the topic. Just need to move to it and through it more smartly.

Sometimes that may mean starting in the middle and working in both directions, say from CC or CR. Have seen that employed well. Have also failed miserably myself in attempting to do it, so that is not a panacea.
