Thanks. Even so, I still come up with a highest score for lasers, oddly enough..
For a score, I multiply all the good parameters and divide by the bad ones, but I take the square root of two parameters that I consider of relative importance. My formula is:
score = ( damage * velociy * sqrt(range) ) / ( consumption * sqrt(delay) )
I use the square root of the range because the further the target, the less likely to hit it anyways, and the square root of the refiring delay because although the amount of damage per second is inversely proportional, the consumption per second goes up as well, which is a semi-dubious consideration, as it depends on power avalilability and usage style. And the winner is...
Laser 83.56 *** gold medal ***
Tachi 61.04
ION 37.51
Plasm 34.56
Partic 33.14
Neutr 27.04
I did not include price in the formula, since it becomes irrelevant later in the game.
So, I sold all 4 tachion guns and particle turret, and went laser across the board, and indeed I seem to slice and dice a lot faster. Good old lasers... who would have thought?
Note: I do consider exit velocity as being "fully" important, in the sense that with a non-linearly moving target, even if using auto-tracking, the hit probability is roughly inversely proportional to the time between aiming adjustment and arrival time.
