where you think ill be ranked- know its bronze but what 3, 4 or 5, 3 long shot

so i have finished 8 placements and im 3-5 heres the scenarios

3-7 where am i ranked? i say bronze 5 4-6 where am i ranked? i say bronze 4 or 5 5-5 ranked? i say that should be bronze 5

keep in mind last season i went i had 3 or lower wins and was bronze 3 then dropped as i played ranked way to early, as in once i hit 30

edit: i calculated my kda through 7 games, its 2 and i have a perfect game that i didnt include since i didnt kno whow to calculate that
