Is PALMBUX calculating honestly the value of my clicks?

Tweet

Following many recommendations of myLot friends I recently have signed up for Neobux and Palmbux. I haven't got rich yet. But while Neobux allows me to click 4 ads per day and credits 4x 1 cent = 4 cents, I feel tricked by Palmbux: They credit 4 ads x 0,8 cents .... but my total amount doesn't grow by 3,2 cent per day. It is about 2,8 cents only. Do you guys observe the same incorrectness?
