Alright, I ask then here.
1ST + Small Frame -> 38 Carryweight?
With Pack Rat support perk -> 38+12 = 50 Carryweight?
And what about this then?
1ST -> 42 Carryweight?
With Pack Rat support perk -> 42+14 = 56 Carrryweight?
If anyone please will explain, if something is wrong with Pack Rat bonus or with starting Carryweight?
Edit: I know that Pack Rat give bonus, depends on your ST.
