In my opinion, the critical error difference is determined by the range between you and the target. At close range you can be off quite a bit (say 5 to 10 degrees) and still get a good firing solution. At greater distances a couple degree error will really throw off the figures. I have never tried to see how much. That's why you need to make several estimates as the target/sub decrease their range separation.

By looking at your trainer, the Nagara Maru is close. So, I'm thinking a 4 or 6 degree difference could be tolerated for a good firing solution.
