After approximately 30 rounds at the rate of three to four rounds per minute the crew of eight officers and 25 men abandoned ship in one lifeboat and two rafts. U-507 approached the tanker close to the port side and put more then 100 rounds into her. The wooden bridge was set on fire and three men were killed. FEDERAL settled on even keel, then listed to port, capsized and sank stern first an hour after the first shot was fired.
(Devastating attack, sunk in one hour).

This is not a counter-example. It's only a bit faster than my rates of fire list I posted above. If anything, this example confirms my figures. 24 rounds would have been fired at a rate of about four rounds per minute on average. Only the last 6 shells would have brought down the average. For the first rounds my figures fit pretty well. For the last, my figures show that a U-boat could put 70 rounds into a target in an hour. Plus, my average figure has to assume that the player is firing a lot of ammo (not just 30 rounds), and there's the fact that U-boat deck guns in the game are far more accurate than real life deck guns.

23 Apr 1942 - At 1120, the unescorted Reinholt (4,799 grt) was attacked by U-752 with gunfire for about 20 minutes. The U-boat fired about 40 rounds of which 20-25 hit, but had then to break off the on Apr. 23-1942, when on a voyage from Santos to New York with a cargo of hides, having departed Santos on Apr. 6, according to the cattack because two destroyers were spotted. Reinholt had returned fire with 14 rounds from the stern gun without success. The Reinholt had caught fire, which was brought under control by the crew after 20 minutes and reached New York the next day.
Shelled continuously for 20 minutes by U-752 (Schroeter). Reinholt's gunners replied by firing a round every 30 seconds, but while they were defending the ship, it caught on fire after having been hit where the ammunition was stored, so after 14 rounds had been fired they could no longer get to the ammunition.
(40 rounds in about 20 minutes, ship saved-merchantmen replies with a round every 30 seconds!)

My figures (above) account for 40 rounds in 27 minutes. It's just not that far off. Plus, (again) my average figure has to assume that the player is firing a lot of ammo(not just 40 rounds), and there's the fact that U-boat deck guns in the game are far more accurate than real life deck guns. As for the ship's ROF, what does that have to do with it? The ship is not a U-boat.

3 Apr 1942 - At 0340, the unescorted and unarmed David H. Atwater was attacked by U-552 about ten miles east of Chincoteague Inlet, Virginia. Topp had followed her underwater, surfaced and began to shell the vessel without warning and never allowing the crew to abandon ship. 93 shots were fired from 600 yards distance, hitting her with about 50 shots and set her on fire. USCGC Legare observed the gunfire and headed for the ship, upon arrival at the scene 45 minutes after the attack, they saw the vessel sinking, leaving two feet of mast above water.

There is no duration for this. '45 minutes after the attack' clearly means 45 minutes after the END of the attack. Anyway, this illustrates my point about accuracy. Topp, one of the best commanders of the war, with a crack crew, could only hit the target with 53% of his shots. In the game, we can get something like 75% with the AI firing, and 99% with the player firing. If anything, this suggests that my model simulates reality quite nicely. Even if this attack had happened in 45 minutes (which I don't believe for a second) my rate of fire is spot on if you take into account the rate of effective fire. In RUb you would get 45 shots into the tanker in 45 minutes, Topp got 50 in. It's just not that different.
We are not merely simulating rate of fire with RUb's gunnery model. It has to counterbalance the uber-accuracy issue too. Otherwise we don't get a realistic simulation. If you have a perfectly accurate rate of fire but you're using a gun that is that much more accurate than a real deck gun was, you don't have a good deck gun simulation. Plus, if the accuracy can't be adjusted you have to look for other ways to counterbalance the accuracy issue - this could be done by reducing the ammo supply and decreasing the rate of fire. All you've shown me here is that perhaps the ammo supply needs reducing by about 50% to simulate the poor accuracy you've illustrated.
