Initially, when I was using the PK with sonar only updates (PK on), I was firing the first shot at zero degrees spread, the second at 2.5deg left, and sometimes a third 2.5deg right. However, all three were missing long.
When using the O'Kane method, with PK off, I leave the spread at 0deg for all shots. While I was having issues with this initially, I determined the cause to be not clicking the send button twice when setting the bearing. All good now.
I think I've narrowed the original issue down to something wonky with how my PK is being updated by hydrophone/sonar data. If I'm in the periscope view and use the menu to ping and send information to the PK it gives me a feedback, but if I double click the feedback changes slightly. I'm going to test more to narrow it down.
