Rake Tracking of the poker room you play in.
Our programmer was working on the code for this poker room today, and it looks like the detailed view summary only displays the current days rake and not the summary of the month so far.
So even the $21 rake you saw on 5th of August was too little, as it was the rake for 5th only. You have made a lot more rake so far this month.
Thank you for pointing this out; we'll work on fixing it. In the meantime I will PM you your daily rake so far.
The daily breakdown of rake is also missing, but will be added back soon.
