I figured my take on it would draw some attention.
Danny, you are right... it absolutely does depend. But what does it depend on? It's a result of the senior rater's boss (NAF/MAJCOM). What I said in my post has been the case as I've seen it in AMC. I gather from your posts over the years that you're a CAF guy, and it wouldn't surprise me to learn that bottom lines of OPRs are yet another difference between the two communities.
You are correct about the Maj vs FGOs strat. I thought my logic of giving a Lt a CGO strat would translate into a Maj receiving an FGO strat, as I was trying to prevent posting a wall of TL;DR words. Giving a Capt a CGO strat is padding the denominator. Capts are supposed to perform above Lts. That's not always the case, so that's why you'll see Lts with CGO strats. The same is true for Majs.
I get what you're saying about my "fluff" comment, but I still disagree. You either have a strat, or you don't. I never said you're hosed if you didn't pull a strat, and yes, the language used does help to differentiate between dead wood and solid citizens. But, to lump a rater saying a guy is "top tier" into actual stratifications is simply apples and oranges. It's a nice way of saying "not my top 20%, but close". Depending on where I was at in my career and who was saying that about me could lead to a little bit of concern.
