Trying to troubleshoot Leaderboard inconsistencies.

I've created a leaderboard for our Discussion forum.  The leaderboard is missing a lot of points!  

I've created another board in the admin page using the same date range and same exclusions (none).  Can someone please take a look and help me figure out what I've done wrong/missing.  Could it be something in the way I set up the rules to award points?  

See images below - highlighed user is the same on both leader lists

User points actual.  The Public leaderboard is picking up the entry from feb 6th and the 3 points from April 24.
