Why is it that a contestant who has had negative equity and been under $2000 in the past would still have the same average end of month equity for the entire time that he has been in the contest? This contestant has been in the contest for more than 12 months and his average end of month equity has not changed. Why is that?

you don't know maths? add all his month end balance and divide it by no. of months in participation. if there are any difference in balance you got and it's showing then post here.
