This graph was compiled by me when the new bazooka and panzershreck deviation was being tested. Each of the datapoints counts for at least 20 shots. The target was the rather large side of an M3 Grant. A hit was called if the Grant either died or started to smoke.
Obviously, these statistics are a 'best case', actual performance will vary. As a side not, these are now innaccurate when non in ironsights.
The bazooka has a velocity of 80, meaning a flight time to 100m of 1.25s.
The panzershreck has a velocity of 110, meaning a flight time to 100m of 0.91s.
Due to these new higher velocities, drop is now negligeable over the effective range.
I believe the PIAT is now also affect by deviaton, but only becomes noticeable innacurate after the max range on it's sights.
