Formula Help
« on: December 21, 2007, 11:30:03 AM »
Hi, I'm trying to work out a new points structure for our league and I wondered if this was possible to do

Quote
Average points doubled, must play 7 games or more to qualify, 0.5 points added every time you play

current point system is

Code: [Select]
switch(r, 1, n,
  2, if(n >= 4, n-2*r, 0),
  3, if(n >= 6, n-2*r, 0),
  4, if(n >= 8, n-2*r, 0),
  5, if(n >= 10, n-2*r, 0),
  6, if(n >= 12, n-2*r, 0),
  7, if(n >= 14, n-2*r, 0),
  8, if(n >= 16, n-2*r, 0),
  9, if(n >= 18, n-2*r, 0),
  10, if(n >= 20, n-2*r, 0))

(so is based on number of players)

Would it be possible to do this, I have been thinking about it for a while and without writing it out by hand Im not sure how to acheive it

Yes,

In the stats filter tab put "points" in the tournament scoring and I think:

if(n >= 7, average(scores) + 0.5*n, 0)

will work for an overall score.

That is assuming you want to add the half-point after they have been averaged (?)

yeah the half point is to be added after they are averaged....

is TD able to sort out a decent way for Hits... in that we are planning on awarding 5 every time someone knocked out someone, but no points, can TD keep this registered?

Have you tried bounty chips?

check out section 8.1.1 of the help tab that describes bounties.

Bounties are simply a fee paid to a person who knocks out another player (so for each hit you would give somebody 5pnds and that is considered a bounty).  Or you can assign a bounty for a specific person (say the previous tourney winner).

Some people give each player a bounty chip .. . a non tourney chip that simply represents the bounty amount and the person who knocks out a player gets their bounty chip (sometimes I use bounty bracelets, those silicone bracelets like the Livestrong bracelet instead of a bounty chip).

the help section above descrives how to include a bounty in your tourney structure

Ignore it.  It's a bug in 2.4.3 that the "points" variable isn't recognized, but it's only in the dialog.  It will still work in the formula itself.

Not sure what to tell you.  I just tried this with version 2.4.3 and it works just fine.  If your Overall Score formula is as you posted earlier:

if(n >= 7, average(scores) + 0.5*n, 0)

... then that will give 0 points to everyone unless there are at least 7 tournaments being filtered.

if(n >= 5, average(points) + 0.5*n, 0)

doesn't seem to give anything but zero even after 5 games =/

I think, but am not sure that you need to use "scores" rather than "points"
