Radio Contact Reports: Contact Reports should be made from a long distance--even out of sight--of an Convoy/TF. It would be great if the player could enter the Location, Base Course and Speed of a contact. Responding AI units would react to that report. If the report is inaccurate, the more likely the AI units will miss contact. Big Reknown should be awarded for accurate contact reports.
Battle Results and Reknown: The Captain should determine whether a torpedoed ship sank and what its tonnage was. Damaged ships should be included. The more accurate the report, the better the reward. "Schepke tonnage" should be possible

.
Ships less than 500 tons (except SC's type warships) do not count as tonnage. Sampans, fishing boats, Sea-trucks etc were not included in the tonnage totals...
