Change in scoring?

For some oddball reason, instead of my usual 120 points over a ten hour persiod last night I've managed to accumulate 220 which leads me to ask if there's another server glitch (I do know the online scoreboard was down for a while) or the scoring system has changed.

I'm not complaining - just curious. By the way, I've left the client running and it's still clocking up 2 points per hour, 11 hours after I started.
