and i am saying it is impossible to calculate it that way from table on enlisted roll call.
- number of total matches is unknown. players can have multiple vehicles per match or they can have one vehicle. lots of matches from same faction overlap cause players have multiple vehicles in their loadout.
- matches need to be divided by BR cause it is pointless to calculate popularity of BR1 vehicle in BR5 match. even then there are players who bring lower BR vehicle in higher BR match and table on roll call doesnt separate that.
if you want to know popularity of vehicle, then you need total faction number of matches divided by BR, number of players that had certain vehicle equipped at that BR and then sorties. that way you will see how many players have certain vehicles equipped and how often they spawn them.
