I think I've figured out what the highest point total so far can be, if it might help:
The contest started November 20 and up until and including today, there have been 16 days. You and your partner can receive a total of 3 points per day for the message board and your survey. so 96 points so far from regular daily activity.
There was 1 opportunity for bonus points, which would earn you 25 points each. So 50 total per team could be earned at the bonus opportunity.
Therefore, as of today, the highest point total would be 146
Tomorrow, the highest point total will be 152 and plus 6 every day after that.
