I don't know about you but I really like hitting the dance button when I am capturing an objective! We should get major points for that. Doesn't seem to make a difference!
Sitting down when you see an enemy try to snipe you. After they miss if you get up and snipe them afterwards, start dancing for 5 seconds. If you live through that. Instant super charge. I think the coding behind that with so many other variables and timers would be difficult. Of course if the sniper hits you, your super charge goes to zero
