I think the Navy's entire promotion system needs to be revamped. Keep all of the current components [written exams, Performance Mark Averages, Time-In-Rate and Service-in-Paygrade, PNA and award points], and add in an oral board and possibly even a practical exam or two. Ideally, the oral boards and practical exams would be conducted by personnel from outside the individual's command (for an added layer of objectivity). And finally, the weight given to the written exam needs to be reduced considerably. IMHO...
