This reminds me of the dreaded "Permanent Record" that the nuns told me would follow me wherever I go for the rest of my life.
Nobody has ever asked to see it except for when I needed a high school transcript to prove that I actually went to one. It was a single sheet with xeroxed copies of my report cards. PERIOD. Nothing about the detention I got for pouring a bucket of water on David Deptula's head in fifth grade. NOTHING!!!
Nobody gives a rodent's hindquarters what some 27 year-old MMC with almost no training in personnel management wrote (or more likely boilerplated) about you when you were 22.
HOWEVER, those worthless pieces of paper are very important to advancement, thus important to one's assignments while still in the Navy. Therefore, they do directly affect one's resume. So, keep them honest for the love of all that is good, wholesome, and holy. Get the wrong jerk promoted to CPO, and he'll wreak havoc on the nuclear industry (and the nuclear navy) until somebody accidentally runs over him with a Ford F450 two or three times.
