Does not take rocket science to have rater and senior rater comments jive. If a senior rater selects bullets that contradict the ratings comments; a message appears within Lotus forms that will pop-up stating that.
I had to give a Soldier a Marginal and 4/4 because of a needs improvement from the rater. Per the DA pam, that is how it is completed. I still wrote positive bullets of being an asset and to put in positions in responsibility.
Here is the PAM so you can learn.http://www.apd.army.mil/pdffiles/p623_3.pdf
