The Doxxbeat knows where Mori is at all times. It knows this because it knows where Mori isn't. By subtracting where Mori is from where Mori isn't, or where Mori isn't from where Mori is (whichever is greater), it obtains a difference, or a deviation. The doxxing subsystem uses rrats to generate corrective doxxposting to drive the Doxxbeat from a position where Mori is to a position where Mori isn't, and arriving at a position where Mori wasn't, Mori now is. Consequently, the position where Mori is, is now the position that Mori wasn't, and the Doxxbeat follows that the position that Mori was, is now the position that Mori isn't.
In the event that the position that Mori is in is not the position that Mori wasn't, the Doxxbeat has acquired a variation, the variation being the difference between where the Mori is, and where Mori wasn't. If rrats is considered to be a significant factor, it too may be corrected by the Doxxbeat. However, the Doxxbeat must also know where Mori was.
The Doxxbeat guided skeleton scenario works as follows. Because a variation has modified some of the information Mori has obtained, it is not sure just where Mori is. However, it is sure where Mori isn't, within reason, and it knows where Mori was. It now subtracts where Mori should be from where Mori wasn't, or vice-versa, and by differentiating this from the rrats sum of where Mori shouldn't be, and where Mori was, it is able to obtain the deviation and its variation, which is called UNO.
