I was never very good at math (especially word problems). So can someone please explain the rationale for using the square root function in the Twin Cities Underground Poker League Rankings formula? Is it intended to even things out a bit for players who can't make every league tourney or does it have some other purpose?

Also, I think that the league point calculator on the TCUPL web-site (http://home.comcast.net/~jneau/TwinCitiesUnderground05-06.htm) is returning incorrect values. I think this is because the denominator is not being captured within the square root function.

Script is currently:
answer = Math.sqrt(participantCount * buyInCost * buyInCost / totalExpense) / (finish + 1)

I think it should be:
answer = Math.sqrt((participantCount * buyInCost * buyInCost / totalExpense) / (finish + 1))

Much thanks to Doc and everyone who posts on this BB. You all have really improved the enjoyment of our home game.

Thanks.

Then is Rastapete's 2/15 post in this thread correct?

Thanks for the clarification regarding the TCUPL league ranking method. I've recalculated my league standings with the corrected formula (i.e. the denominator is not included in the square root function), and my standings seem to make a lot more sense now.

I think I got confused by the screen shot contained in Rastapete's post at 2/15/06 @ 9:02 pm. The positions of the Square Root and Divide functions shown in that screen shot should be swapped.

Thanks again.

On paper it works just great but on the program it does not seem to reward the people who keep coming back.

Example:

We have a league in wich we played 8 tournaments. Person One has played in al tournaments and person Two only in one (the 6th).

I tried to see if there was a difference in ranking points in tournamant 9.
I let 30 people play the tournament.
First time i eliminated everybody except Person One, who was automatic eliminated by the program. He got, lets say, 10.653 points for 1st place and every body else got 6.324 for being second.

After deleting the history i did the same with Person Two. He got the same amount of points as Person One, even though he had played only one game.

What am i (is the code) doing wrong?

P.S. code is: 2005LeagueFormula

Dr. Neau,

Could you please send me your league ranking method for twin cities.

Thank you.

Dave.

I have been using Dr. Neau's Tournament Manager for over two years now. I have been happy with it and cannot wait for the next version...hope it is Mac-friendly.

To see the ranking method I use for over 100 players in a 10-event "season," visit www.pacesedge.com/poker

I use the rankings to determine chip stacks at the end of the year. The "better" players should have some form of "home-field" advantage was my thought. Gives people incentive to return to the table each Circuit Event as well.

Yes, it does favor people that play everytime, but hey...if Tiger Woods takes a year off...doesn't his ranking go down? I say reward the player that plays each time. That is better than not showing up.

Penny for your thoughts,
