I had similar reviews, both this year and last. The first reviewer actually had some negative comments but gave me VG/E and the second reviewer had nothing but good comments and yet I got a F/G. It's really frustrating to see such differing opinions, it would have been nice to get that 3rd reviewer to clear the air a bit. Still have one more year, hopefully a stronger publication record will help next time.
I had the same feeling!
IM/BI
F/G
E/G
Obviously I needed to expand upon my broader impacts, and the second reviewer made note of this, but a fair and an excellent for IM? The "fair" reviewer really didnt have any insightful criticisms and seemed to be writing a summary of my personal statement and really nothing else. The "excellent" reviewer gave me a slightly more helpful review on BI and really praised my ability as an ecologist or IM. This really just solidifies the notion the GRFP is a crapshoot in my mind. There's always next year.
