The way I comparison shopped was to go CCS Bidding, and Category Award Reports (I think that is the title). Middle tab once "Bidding" opens.
Scroll until you find a BES you are interested in. Open it, and scroll down until you find where your seniority fits.
Look and see what guys a few above and below you are getting.
I don't think it overtly says where the G-line is, but when each award turns into Reserve, you've found it, plus or minus a couple.
I used this to bid my fleet, and am very glad I did.
You can also go to CCS "Reports," and select "Staffing" from the drop-down.
Very useful and helpful.
