The World of Warships version of Plymouth is used for a magazine-endurance calculation. Sixteen six-inch guns firing every three seconds would send 320 shells per minute toward a target. At an assumed 200 rounds per gun, the 3,200-round magazine would last only ten minutes at that sustained rate. Doubling the allowance to 400 rounds per gun gives 6,400 shells and about twenty minutes of fire. A reported game total of 5,000 rounds prompts the question of where that ammunition would be stored. The arithmetic applies a real supply constraint to the game's firing rate, without treating game ammunition behavior as a historical ship characteristic.

Plymouth's game rate of fire against a finite magazine
A game cruiser's rapid reload shows how quickly high volume of fire would exhaust a finite naval magazine.
