# WIP Scores
# L'idée c'est de donner un score pour mettre un peu de challenge en pénalisant les preums faciles.
#
# Un preums ne vaut pas 1 point, mais plutôt 0.10 ou 0.05, et on arrondi au plus proche. C'est un jeu sur le long
# terme. Un gros bonus pourrait apporter beaucoup de points.
#
# Il faudrait ces données:
# - moyenne des preums
# - activité récente du channel et par nb actifs d'utilisateurs
# (aggréger memberships+usertrack last_active ?)
# (faire des stats d'activité habituelle (un peu a la pisg) ?)
# - preums consécutifs
#
# Malus:
# - est proche de la moyenne en faible activité
# - trop consécutif de l'utilisateur sauf si activité
#
# Bonus:
# - plus le preums est éloigné de la moyenne
# - après 18h double
# - plus l'activité est élévée, exponentiel selon la moyenne
# - derns entre 4 et 6 (pourrait être adapté selon les stats d'activité)
#
# WIP Badges:
# - derns
# - streaks
# - faciles
# - ?
