I have 5593 Strength from gear/Gems/ enchants and 192 base strength and 9 from plate specialization from base. That's 5794 and I have 5811 in game. With that being said i'm missing 17 strength somewhere and plate specialization should be in the neighborhood of 169 which isn't being taken into account. and from plate gear I multiplied 3384 by .005 and got 17...... I'm lead to believe there's an issue here.
I do have my calculations on an excel spreadsheet for a dev.
