According to the invention a device has a calculation unit distributing value units into a first and a second group, setting a first counter value and performing comparison value dependent calculations. In these calculations it receives a selection of all value units in the first group or one value unit in the second group, compares at least two comparison values with each other and increases the number of value units in the first group if the user has selected all the value units therein or in another group if the user has selected one value unit in case the comparison is in favor of the user, or otherwise removes all selected value units. The calculation unit repeats the calculations and changes the counter value each time calculations are performed for only one value unit, and otherwise resets the first counter value and automatically selects all value units in the first group in the calculations if the counter value has reached a second counter value.
