## Point System for the 2008 World Fly Fishing Championships

### Description

Point system for the 2008 World Fly Fishing Championships: current and proposed.

### Usage

    wffc.P1(length, min.eligible = 0.18)
    wffc.P1star(length, min.eligible = 0.18)
    wffc.P2(length, min.eligible = 0.18)
    wffc.P2star(length, min.eligible = 0.18)

### Arguments

`length` | Length of the fish, in metres. Numeric vector.
`min.eligible` | Currently the regulations stipulate that the smallest eligible fish is 180 mm.

### Details

The official website contains a document with the official rules and regulations of the competition. The function `wffc.P1()` implements the current WFFC point system. `wffc.P1star()` is a `continuous' version of it.

The function `wffc.P2()` is a new proposal which rewards catching bigger fish. `wffc.P2star()` is a `continuous' version of it.

### Value

A vector with the number of points.

### Note

`wffc.P2` and `wffc.P2star` may change in the future.
