The Bone Yard

I feel like I should preemptively state that I really like the 247C and in no way intend to rip on it -- I just have some questions about how it works. I noticed immediately after gaining two commitments yesterday, Nebraska dropped from 18th to 20th -- this, despite moving up to 14th in Rivals, maintaining rankings on Scout and 247, and gaining an ESPN 4-star in Dixon (ESPN hasn't updated rankings since the 17th).

From this info, I gather that the 247C ranking has absolutely nothing to do with other services' team rankings (which makes sense, and probably could have been easily deduced earlier). I assume it's the same formula as the standard 247 ranking, but using Composite scores instead. I also assume this means 247's equation has a heavier average-rating component than Rivals' (which is a good thing, IMO). Can anyone give me a more in-depth description of how the 247C rankings work, or point me to someplace I can read more about it? I found some older posts generally describing it from when it was rolled out, so any info beyond that would be appreciated. Also, is the Composite made up of 247, Scout, Rivals, and ESPN, or is there something else in there?

Thanks!
