@20GT: They could assume that the weight of X at the start is the same as the average of the others, then
(summed weight loss) = 4/5 * (starting weight of 5)  (final weight of 4) I don't see reasonable other assumptions. @disregardthat: I don't think it is reasonable. If X is heavier than average, you get a lot of imaginary weight loss (formula gives a large result without actual weight loss of anyone).

It is more likely he he closer to the average of his group than the average of everyone since he participated in his groups initial weigh in.

That makes it 20% less bad (as 20% of the weight* in the average comes from him), but still problematic.
*the mathematical weight, not the one in kg.
