I don't know if it was cooincidental or what, but I had mine set to the same score for a while and got no changes while drastically paying down balances.

So I changed the score to check for my score+1, and got a notice the next day. Changed it again to that score+1, and got another alert the following day.

So either there was a delay and the messages hit me back to back days, or changing it to +1 did the trick.. or some other mysterious power 

Either way, a 29 point jump over a 2 day span made me happy.
