Long time manager, and I agree with all of this, but I also identify with OP and also get only a handful of hours of work done every week and I've wondered the same thing.
I get high marks (high to superlative performance) consistently, but it's usually because when I deliver, it's with high quality outputs and effective delegation. Otherwise I don't really do much but wonder whether I'm really under performing if all my reviews are as strong as they are, or if I just do the work more quickly than most others.
edit: I'm fine with this comment being dead, honest. less people see it and less risk of me being identified on my main. don't vouch. I'm using tor so that's why
