I've found great assistance with the guys from the CRS bid assist. Email them with your questions and they will be very helpful. I've found their advise to be very helpful. If only to distinguish bid mistakes from "manual insertions".
They will happily email you the CRS bid results with a short explanation. or even better go the crs helps sessions and talk to them.
But remember, they're line pilots like you and me and do this in their spare time...
