Since most of the variables used in the rankings are already in system, wanted to see how easy it would be to get user defined scoring. We currently use the Log method, but we have run into some issues (posted additional comments under home tourney). I guess the 2 options I'm looking for is:
1 - ability to multiply the ranking by number of entrants. Example: using log method, first place in 6 person tourney gets 1.95 points. I want the ability to multiply by 6 to get a score of 11.7
2 - ability to not include high/low score to even out rankings. Or even ability to pick best n tournaments.

Finally someone else requested the same thing as me..........I would love a user configable league ranking system.........I didn't get a lot of response/input the last time I requested this......

I wouldn't think it would be that hard, Doc. But then again, I'm not a software developer - I just help planes stay in the air...

Gotta agree, I think this would be a nice feature.

Finally.....more support for this feature........

Hey Doc.....could the program pull a formula out of a text file......(if you create one with the correct varables).......

Work has begun.

Of course, when it comes, this feature will only be available to those paying for extended features.

More on the work in progress...a peek into how I'm developing it.

A league ranking system actually consists of 2 formulas:
- The tournament scoring formula (a player's score for a given tournament)
- The league ranking formula (how tournament scores are combined into a league score...like "total", "average", etc. Also might be minimum # of tournaments).

Details on the tournament scoring formula system I'm coming up with...

A tournament formula consists of a numeric expression.

A numeric expression can be either a numeric formula, a numeric variable or a numeric constant.

A numeric formula is one of the following: add, subtract, multiply, divide, min, max, abs, ceil, exp, floor, log, power, round or sqrt. The operands of a formula are another numeric expression. So, if you wanted to add two sqaure roots, you'd really have a numeric formula (add) with two other numeric formulas (sqrt) as the operands.

A numeric variable is a numeric attribute of the player or the tournament: player's buy-in expense, add-on count, add-on expense, rebuy count, rebuy expense, bounty, bounty revenue, knockout count, total revenue, total expense, net gain, finish or place revenue. Also could be tournament buy-in count, add-on count, rebuy count or gross prize pool.

A numeric constant is just a number.

I'll also consider (later) adding formulas that having boolean logic embedded in them, like "if".

So, you'll be able to construct extremely sophisticated formulas. Sound like I'm on the right track?

The domain logic is there. Now I need to GUI-ize it...give you an easy intuitive way to construct the formula. Then I need to work on the league ranking formula. Then I need to let you save it and load it (probably in a special file for formulas defined in the properties screen).

Here's what it looks like so far. Getting close....

The first one is the "log avg" formula that I normally use. The second is what Clay's formula might look like.

I'm going to add more options to the "score accululation" area:
- Average, total, decaying weighted average or decaying weighted total for tournament scores. (decays give more weight to recent tournaments)
- Post ranking adjustments, like automatically pushing tournament winners to the top if you want.
