I have always used 0% MDH, but I have seen many games use 100% (PUBG, Fornite, Destiny 2, Valorant, Splitgate, Back 4 blood). What would you do, keep using 0% or change to 100% and get used to it. What I dont like of 0% is that, in those games I have to chose a sensitivity for one zoom level and if I use another weapon with different zoom level it wont match 0%, otherwise 100% will always match with all zoom levels. I hope I explained well...
