Calculates the K factor for a team based on matches played.
Uses exponential decay from k_max to k_min.
Usage
get_dynamic_k(matches_played, k_max, k_min, k_halflife)
Arguments
- matches_played
Number of matches the team has played
- k_max
Maximum K factor for new teams
- k_min
Minimum K factor floor
- k_halflife
Matches until K decays halfway
Examples
get_dynamic_k(0, k_max = 40, k_min = 20, k_halflife = 50)
#> [1] 40
get_dynamic_k(100, k_max = 40, k_min = 20, k_halflife = 50)
#> [1] 22.70671
