So that means that the summarization algorithm is wrong and needs 
serious improvements.

Can you explain to me how the answers from LS as shown by Nina can help 
the GUI to get data from PIONIER network as they don't provide *ANY* MA 
which contain correct data? My understanding is the results are 
currently useless for GUI. What would be the way to get correct MAs 
according to this algorithm?
