Well, we have taken into consideration both the rate of fire and reload rate (how long it takes to reload) when applying a "lethality" score to weapons. When it comes to determining how many rounds you can expect to get off in a turn, we have to consider a few things. For example, the submachine gun, we have modeled ours after a typical 9mm UZI, where clip size varies, the typical clip size is 32 rounds. We have elected to model ours after the closed bolt automatic, which can fire something in excess of 900 rounds per minute, but we have attributed a rate of fire of 30 rounds for the game. We take into account things like aiming, delay in targeting multiple opponents, and a controlled rate of fire, to insure accuracy vs an uncontrolled rate of fire, which may use a lot of bullets, will not provide the most accurate results.
In the future we will allow weapon upgrades such as scopes, increased mag. capacity, etc. While this will not affect our rate of fire, it will affect reload rate. In general, you don't need to or want to use en tire clip on an opponent, as it is not needed.
We don't take the decisions we make with regard lightly, a lot of thought and research went into our logarithms, but I appreciate the questions.
