Points System:
P = sum(pi)
pi = (n-x)*k + m
k = (t - x + 1)/t

where:
P - total player's points (sum of points for each track)
pi - points for one track
n - total count of players that finish current track
x - occupied by player place on current track
m - points for medal on current track
k - coefficient of "occupied place"
t - total count of players

Players that finish with same time get same points.
