Total Fixed Rake Calculation
« on: November 26, 2013, 07:13:56 AM »
I'm confused (nothing new there) as to how TD calculates the Total Fixed Rake when running stats. My game uses a 10% fixed rake on $20 buy-in and $20 add-on. Our quarterly tournaments are a $40 buy-in with a 5% rake and no add-on. I have played in 19 regular tournaments with an add-on in each (19 x $4 = $76) and three quarterly tournaments (3 x $2 = $6) for a total of $82. Stats show my Total Fixed Rake is $76.43. Perhaps a better example is the player who has played in 12 games never opting for the add-on (12 x $2 = $24) and TD shows his fixed rake totals $41.42. What am I missing, and--since we deal in even money--where are the odd cents coming from?
If it ain't naked, deep-fried or poker-related, I ain't interested!

The Fixed Rake is a fixed amount taken from the pot.  It's not a per-player amount, but the Stats tries to compute it that way so you can see what kind of impact it has on a per-player basis.  What it does NOT do is take into account each player's contributions to the pot and weigh the player's fixed rake amount appropriately.  It just spreads the fixed rake evenly among players.  So in that sense, it isn't accurate.  Then again, it's not a per-player amount.  And how a non-per-player amount is computed on a per-player basis is, I think, a matter of opinion.

In your example you've configured a 10% fixed rake with a $20 buy-in and $20 add-on.  Let's say you have 10 players, and 5 add-ons were purchased.  That would make the pot $300.  A 10% fixed rake means $30 would be raked.  Each player's Fixed Rake "contribution" would be computed as $30 / 10 players, or $3.  That's what you'll see on the Stats tab.

As an example of the other way I described it could have been implemented, let's say one player bought in and purchased 3 of those 5 add-ons.  His expenditure would have been $80, which would have been ($80 / $300 = .26666...), or roughly 26.667% of the pot.  The fixed rake would still be $30, but his part would have been $30 X 26.667%, or $8.  I would argue this is more accurate, but again, it's somewhat a matter of opinion, and unfortunately that's not the way I implemented the Stats computation.

If you put a $2 rake in the Buy-in profile, and the a $2 rake in the Add-on profile, I'm sure your per player figures would then be accurate.
