I have 257 scout controls and only 233 scout scans. I have scanned some portals up to 5 times.
Controlling Volatile Scout Control Portals is worth 3 points per VSCP instead of 1 point.
Some portals (so called "Volatiles")give you three Scout Controller points, those are the ones with a yellow rotation square in the Scout Laywe view. Even if you did scan a few portals multiple times, if you have scanned a lot of these Volatiles, it's possible to have a higher Scout Controller count compared to Scout.
and you can get controller too when the 30 days of control expires.
