I have played SH3 with 100% realism for years and I can bullseye ships with manual targeting. I am not hitting anything now.
I am doing 90 degree attacks. I both a parellel run and the stopwatch to determine a speed of about 6 knots. I dialed in 90 degree port AOB (I was approaching the targets 90 degrees from the target's left) and set my gyro to 0, which resulted in a lead of about 12 degrees to starboard.
I fired well inside 1000 meters 3 times and missed, including twice with a 2-shot spread.
I'm using WoS modpack so I can't tell if I missed ahead or behind the targets as map contacts are off.
This should have been a no-brainer shot.
