ABP

Here's my best guess.
Normally rep power is visible as a string of boxes. You'll see this a lot on other forums where there's some type of icon, and perhaps only 3 of 10 are filled in.
Rep power is nornally not a single box, so I am guessing that reputation here is displayed in the single box you can see, and is summarized as "positive" (will be a green box) or "negative" (will be a red box). I'm also assuming that, since it's either green or red, the reputation is averaged.
Again - with a lot of LBT-specific questions, all I can give is best guess or answers based on common practice, so I can't ensure this is the right answer.
