I have made the point in an earlier thread that the game should make it easier for players to review what they are receiving via convoys. At the moment, you get a quick screen flashing by at the end of your turn listing the amount received per convoy but unless you screen capture it, you can't review it. And seeing how much a convoy is down is the only way to know if your opponent is raiding your convoys. The graphs show total amounts received by convoy but not broken down. This is particularly an issue for the U.K and to a lesser degree Germany, since both powers have multiple convoy routes.
In contrast, it is relatively easy to see what impact your raiding is having on an opponent's convoys. It is broken down by raiding ship, convoy route and MPP amounts in the Military Effects Summary which you can call up at any point during the next turn by pressing a hot-key.
I appreciate the overall principle of fog-of-war but I don't understand why the information about what you receiving via convoys is "foggier" than what you are sinking in enemy convoys. Surely, a power would have more accurate records about the cargo vessels that reached their ports every turn, where they came from versus what was expected, compared to what their navies claim to have sunk against enemy convoys.
