Ok i understand
The betting player on 03/28:
So in the case of poker … you can see a ‘betting player’ and no rake when they play in a freeroll.
When a player plays on such a small table limit that the pot isn’t raked – would have to be very small <$.5/1 in almost all cases. Also there are some abstract rules re: heads-up play where sometime the pot isn’t raked This is taken from this post: http://www.casinoaffiliateprograms.com/bb/betting-players-but-no-rake.9563.html?
As for the betting players on 03/29 – the reason it was there one day and gone the next is because there was a database lock. What this means is that when the stats sync, for about 10 seconds the stats are deleted and re-synced with the new stats. The database deleted the old stats, but didn’t insert the new ones because it was locked.
As you can see, the table has been re-synced (since the database lock) and the profit/loss is now showing.
If I still have misunderstood your question let me know… I am known to be blonde sometimes
