PROBLEM TO BE SOLVED: To provide a system for a game hall, which accurately extracts a nail adjustment candidate machine or nail adjustment candidate date in execution of simulation of nail adjustment data for a plurality of days. SOLUTION: A data management device sets, when "current S value" that is a simulation value of a date corresponding to game data that is a determination object is differed from "next S value" that is a simulation value of the next business day, a reference value for allowable range to the "next S value". According to this, when the "current S value" is differed from the "next S value", the possibility of false nail adjustment which is performed based on the nail adjustment performed on a business day performance data is obtained in spite of the unnecessity of nail adjustment can be eliminated.
