Has anyone done the math on the 2018 WSOP POY formula? http://www.wsop.com/2018/POY/

Based on the \$3k NLHE tournament, I found the math, and came up with the formula for the top 9.

round(switch(r,1,477.45,2,238.75,3,214.845,4,190.97,5,179.05,6,167.1,7,143.25,8,131.27,9,119.35)*pow(n,0.125))

I need help with the final parts of the equation.

next 20%: 95.49*pow(n,0.125)
next 30%: 47.745*pow(n,0.125)
next 50%: 23.875*pow(n,0.125)

So this is for the top 9 finishers?  And 'next 20%'  means the next 20% of finishers?  So if there were 100 players, the "next 20%" would be ranks 10 through 29?

correct. In the actual WSOP, it would be next 20% of ITM players, but I'm wanting to modify for our league.

OK, here's what I came up with.  I worked on this, realized I wasn't doing it right, started to re-work it, and had to leave for a while.  Hours later I picked it back up, so I could be completely off in la-la-land at this point.  Keep that in mind.

assign(p, n - 9)
assign(p20, round(p * .2))
assign(p30, round(p * .3))

round(switch(r,1,477.45,2,238.75,3,214.845,4,190.97,5,179.05,6,167.1,7,143.25,8,131.27,9,119.35)*pow(n,0.125))
+ if((r > 9) and (r <= 9 + p20), 95.49 * pow(n, 0.125))
+ if((r > 9 + p20) and (r <= p + 9 + p20 + p30), 47.745 * pow(n, 0.125))
+ if(r > p + 9 + p20 + p30, 23.875 * pow(n, 0.125))

First, "next 20%, 30%, 50%" implies that the remainder of the players, after the top 9, must add up to 100%.  So those percentages are referring NOT to the total number of players in the tournament, but the players in the tournament minus the top 9.

So I found it easiest to compute the number of players remaining, and 20% of them and 30% of them.  That makes the actual formula simpler.  We don't need to compute 50% of them because that's simply what is left.

Essentially each line awards a "class" of player.  Either you're in the top 9, or the next 20%, or the next 30%, or the next 50%.  Any player will only qualify for one of those categories, so adding them up is fine, since 3 out of 4 will always evaluate to 0.

I hope the rest is self-explanatory.  Let me know if there are questions.  And check my math.  The odds that I made a mistake are high. #### efdenny

Not quite there... not sure what's missing, but it's only assigning points to the top 9.

Would you believe I worked on this and tested it to the extent that it didn't error, but didn't really see if the values were correct?  I would.

The variable names in the "assign" statements need quotes:

assign("p", n - 9)
assign("p20", round(p * .2))
assign("p30", round(p * .3))

round(switch(r,1,477.45,2,238.75,3,214.845,4,190.97,5,179.05,6,167.1,7,143.25,8,131.27,9,119.35)*pow(n,0.125))
+ if((r > 9) and (r <= 9 + p20), 95.49 * pow(n, 0.125))
+ if((r > 9 + p20) and (r <= p + 9 + p20 + p30), 47.745 * pow(n, 0.125))
+ if(r > p + 9 + p20 + p30, 23.875 * pow(n, 0.125))

LOL! Much closer... just a bit off though.

As an example, for a 21 person tournament, taking the top 9 out because those are correct, the scores should have been:

10 & 11: 140
12-15: 70
16-21: 35

However, with this formula, 12-21 are all getting 70. Thoughts?

I figured it out... you don't actually need "p" in the last two parts of the formula:

assign("p", n - 9)
assign("p20", round(p * .2))
assign("p30", round(p * .3))

round(switch(r,1,477.45,2,238.75,3,214.845,4,190.97,5,179.05,6,167.1,7,143.25,8,131.27,9,119.35)*pow(n,0.125))
+ if((r > 9) and (r <= 9 + p20), 95.49 * pow(n, 0.125))
+ if((r > 9 + p20) and (r <= 9 + p20 + p30), 47.745 * pow(n, 0.125))
+ if(r > 9 + p20 + p30, 23.875 * pow(n, 0.125))

Dangit, I just came to the same conclusion but didn't look to see that you had figured it out first.

Also, you wanted it rounded, which I omitted.  So just take the close parentheses off the end of the first line (after the assigns) and put it at the end:

assign("p", n - 9)
assign("p20", round(p * .2))
assign("p30", round(p * .3))

round(switch(r,1,477.45,2,238.75,3,214.845,4,190.97,5,179.05,6,167.1,7,143.25,8,131.27,9,119.35)*pow(n,0.125)
+ if((r > 9) and (r <= 9 + p20), 95.49 * pow(n, 0.125))
+ if((r > 9 + p20) and (r <= 9 + p20 + p30), 47.745 * pow(n, 0.125))
+ if(r > 9 + p20 + p30, 23.875 * pow(n, 0.125)))
