Need Help adding please, something is wrong

When i am using 26SAB / 20BD / 20Sin spec
While equiping Equalizer
Str +19
DEx +26
Ap +15
Crit +24
hit +35
+9 Ap rune
(Should be 50 crit, 69 Ap if math correct)
I have 829 Ap/1000Crit

When i Equip
Nihilist Rifle
Str +27
DEx +32
End +26
Ap +18
Crit +20
(+13 hit rune)
(Should be 48 Ap/ 52crit if math correct)
I have 830Ap / 1003 Crit)

I am not a rocket scientist or anything but 50crit and 69 Ap swapped over from 48Ap 52 Crit Should not equal a 1 Ap and 3 Crit gain overall...what am i missing or doing wrong here, i shouldnt complain obviously cause i shouldnt be gaining anything in overall stats but lossing ???

The second question is Should i be swapping out the ranged weapon if i am Changing from a melee sab spec to a 51mm 15 ranger spec Equalizer base dps being 41.7 and nihilist rifle being 55.0 or is there something hidden here im missing?

Alot more Str and Dex +3 more raw ap = your issue. Read your tooltips carefully, you'll figure it out.

Naw i added the str/dex and raw ap from equalizer instead or adding str/dex and diving by 2 ....figured this out 10 sec after post i promise im not a total ******....only half

while equiping equalizer
str +19
dex +26
ap +15
crit +24
hit +35
+9 ap rune
(should be 50 crit, 69 ap if math correct)
i have 829 ap/1000crit

(19/2) + (26/2) + 15 + 9 = 9.5+13+15+9 = 46.5 ap
