Using the "initial data" and various Screenshots posted by ObiWanKenobi2016 I put the data for SQUAD TOTALS and COMMANDER TOTALS for each FACTION into Microsoft Excel and created two "Trend Charts" as follows:

- The overall "trend" for the number of Squad per Faction shows a continued slight ⬆ Increase.
- The overall "trend" for the number of Commanders per Faction shows the Empire Faction having a ⬆ Increase, while the Rebel Faction shows a continued ⬇ Decrease.
- It is a continued hoped that once Zynga starts taking control and releasing game updates that there will be a reverse of the downward trend of Commanders especially for Rebel Faction.
