Take base damage to be 100 Increase or decrease in speed or damage per shot changes this proportionally. Thus: 100 + 20% = 120, 120 - 10% = 109.1 So damage is increased by 9.1%.

However, the best use for these modifiers I have found is by combining them with laser beam type weapons. If you can bring them below 20% health with just laser beams, by adding an overcharge, that 20% is dealt with the first shots. This means that the overcharge can reduce the number of shots needed to kill an opponent by 1 shot, which is a lot of time if you are fighting a group of opponents.

The overdrive on the other hand would be useful if your first shots bring them to just above 20%, so you can get your shots off faster.
