Question about Pickjack earnings

I do not know how they calculate everything over their at pickjack. My earnings do the same thing. I think that it has something to do with the percentages. so try to answer all the questions so you get the right answers. i know that if questions that you have been answered get removed you lose what you have made. also on the questions that you start if the rating is high you make more. So the better the question that you ask the higher people rate it. I like pickjack very much, and i spend about a half hour their every day. i am working on my 4th payout, so they do pay when they say they are going to. What i try to do with them is balance it out for every question that i answer i try to post a related question,
