This formula is figured out by Andibad. I don't really understand this either. Maybe other players can understand it and explain to you. So far I only know Round is the step that you make a float number and convert it to the nearest larger integer. For EX: The U parameter I guess it is the number of friends accept your Market request during the Market session
 * Round(10.4) = 10
 * Round(20.6) = 21
