I don't know if this is directed at this site and me or the devs of the game, but when they do a full wipe and change everything requiring a quite dedicated grind to get everything back AND analyse it... It will take time. There's over 500 games here now, imagine just a fraction of them doing this. While this game is quite popular, putting everything aside to grind on a single game is not feasible. If you have any anger direct it at the devs of Tarkov who seemingly have no idea how to implement aim and scope sensitivity.
Even if we get every calculation figured out now, it might change next week. Accompanied with a new wipe... A game in development is fine, but in a game where aiming is a key component they should get aiming figured out way quicker than this.
It's not that hard. You either add sensitivity for each available scope power, or you add a scaling that is linked to the scope FOV. Right now they have scopes with identical FOV that have different sensitivity. This makes absolutely no sense, and it seems like they are just randomly assigning sensitivity to scopes.
