Don't let it bother you at all. This isn't unusual. I just asked my staff to do the same thing so I could give her a big promotion.
Seeing her world through her eyes, and comparing it to the value I find in her work is always worthwhile. While I will edit her information prior to sending it to compensation committee, it pointed out some subtle but important things I frankly would have forgotten.
I am doing one for myself as well. My boss is a fabulous boss, but he's not involved in the day to day operations of my department. I can represent myself better to him by providing him with this information to share on my behalf with the balance of senior management.
Toot your horn in a clear and concise way and GOOD LUCK!!! Don't let it bother you at all
