I prefer the cluster sheet. However, the basic music sheet break down for espionage tracking. Is that every major line in a society gets a note. Then each character is placed on the sheet. With the level of propensity to take action against their country for implosion of their ideological foreign masters. Then as such, the basic notes are then played together. Now this can get very deep as we have tracked some MSS units using this theory on computers. Which means basic character physics's and other areas can be implemented into a tracking device which the US does not have. Then the MSS uses it to conduct a sort of symphony. In which sometimes the character does not even know that they are being played like a piano.
That is why Communist music composers where always well known to be the highest espionage agents in the Soviet Union.
