The ECM module follows the same formula for range as all other modules that have a falloff mechanic:

:<math> \displaystyle \text{Jam strength} = \text{Base} \times 0.5^{~~\Large~~ \left( \frac{\max(0,\ \text{Distance} - \text{Optimal})}{\text{Falloff}} \right)^2 } </math>

:<math> \displaystyle \text{Jam strength} = \text{Base} \times 0.5^{ \left( \frac{\max(0,\ \text{Distance} - \text{Optimal})}{\text{Falloff}} \right)^2 } </math>

Going slightly beyond your optimal is not a problem but the effectiveness of ECM will degrade more rapidly as you go further away as seen in the table below.

Line 60:

Here is an example:

let's assume your ECM module has a 50 km range and a 40km falloff. When your target is within optimal range you have a 20% chance to jam them per cycle of your modules.

* If your target is 50 km away you will have the full 20% chance to jam

* At 60 km (50 km + 10 km) you will now have 17% chance to jam (84% of 20%)

<math> \displaystyle \text{Jam strength} = \text{20}\% \times 0.5^{ \left( \frac{\max(0,\ \text{Distance} - \text{50km})}{\text{40km}} \right)^2 } </math>

* If your target is 50 km away you will have the full 20% chance to jam

* At 60 km (50 km + 10 km) you will now have 19,15% chance to jam (95,76% of 20%)

* At 70 km (50 km + 20 km) you will now have 16,82% chance to jam (84,1% of 20%)

* At is 90 km away (50 km + 40 km) you will now have 10% chance to jam (50% of 20%)

* At 130 km away (50 km + 40 km + 40 km) you now have a 1,25% chance to jam (6,25% of 20%)

If you don't see any stand-out targets, like logistics ships, jamming enemy damage-dealers is probably a safe decision. This usually means [[battleships]] and [[battlecruisers]] but the enemy might field a fast-moving gang of smaller ships. The T2 cruiser-sized [[Cruiser#Heavy Assault Cruisers|heavy assault cruisers]] and frigate-sized [[assault frigate]]s are noteworthy smaller damage-dealers, and they don't have very high sensor strengths.

If you're flying a Blackbird, Scorpion or Kitsune you will have a long enough range that you will be one of the few ships in the fleet that might be able to counter enemy snipers. With good ECM range skills, the Blackbird and Kitsune should have a decent chance to jam sniper HACs, and the Scorpion should have a decent chance to jam sniper battleships. (This is where a Targeting Range script can come in useful if you fitted a Sensor Booster.) Keep in mind that your jammed target can still shoot back at you if you're in range, and that damps or tracking/guidance disruptors may be more appealing, depending on the situation.
