you run the iterators always for the whole array.
your intention to count only the selected (posiotion ==...) items could 
not be realized in this way.
Either you build other select queries ( ~ WHERE position == ...) to have 
three arrays only with items with current position
or you build up your own iterator you only increase inside the filtering 
f:if.
