When 200% was buffed to 300%?
Regardless, all that means is they got almost 14 DPS in cover with LMG, which is superior to penals even at vet3(both vet3 that is).
It is not x200% it x150% because of the penalty:
"Captured slot items now suffer from a -50% accuracy penalty, and +300% accuracy bonus in cover no longer applies to them"
In the end it was decided:
"Cover bonus for slot items from 300% to -25%."
Slot weapon ended up having Cover bonus for slot items from 300% to -25% and probably the -50% penalty.
So I you number are probably off.
To clarify the osttruppen k98 DPs is
Ranges 0/10/20/35
Listed as:
2.42/1.858/1.495/1.067
with the penalty actually:
1.21/0.93/0.75/0.53
when in cover
3.63/2.79/2.25/1.59
So a squad with 6 K98 has
21.78/16.74/13.5/9.54
compared to
21.68/15.62/11.90/6.36 of conscripts
Now the LMG probably still has the penalty and if it does have the penalty then it should be
when out of cover:
2.53/3.46/4.04/4.47
and
When in cover
1.90/2.59/3.03/3.35
That would bring the total squad DPS with an Lmg to
No cover 8.58/8.11/7.79/7.12
Cover 20.05/16.54/14.28/11.30
One has to keep in mind that Ostruppen have a target size of 1.25 similar to weapon crews.
But all these is quite irrelevant to riflemen and Calliope.
