| Note that when calculating the chance to jam a single target using a rainbow fit, the above formula must be modified, considering that a rainbow fit will have different jam strengths, per racial jammer, dependent on the target race type. | | Note that when calculating the chance to jam a single target using a rainbow fit, the above formula must be modified, considering that a rainbow fit will have different jam strengths per racial jammer. |
| | |
| So let's use that equation in an example:
| |
| | |
| === Scenario 1 ===
| |
| | |
| Say your fleet is flying around and you come across a scary Caldari Raven. You throw on your sensor booster and get a target lock on him really fast. You are lucky (or unlucky!!) that this Raven is within 50km and inside your optimal range of your ECM modules. You see the Raven start to get a target lock on you (and you begin to sweat a little)
| |
| | |
| You make a quick decision:

| |
| |}
| |
| | |
| <br> What are your chances that you won't get turned into a fine mist?
| |
| | |
| Let's assume that the Raven has no modules active that increase his sensor strength and therefore has 22 points of Gravimetric sensor strength.
| |
| | |
| Let's assume you are flying the Blackbird above with 2 Signal Distortion Amplifiers and no skills to increase your jamming strength; you also only have Caldari Cruisers II (you are a noob) and you have all Tech 1 Meta 0 jammers.
| |
| | |
| First let's calculate your jammer strength:
| |
| | |
| The "ECM - Spatial Destabilizer I" has a Gravimetric strength of 3
| |
| | |
| This will be improved by the Blackbird's ship bonuses and by the Signal Distortion Amplifiers.
| |
| | |
| *Caldari Cruiser II -> 30% ECM jammer strength for a Blackbird which will add : 0.9 strength
| |
| *Signal Distortion Amplifier I (2 of them means one will have the [[Stacking_penalties|stacking penalty]] (87% effective)) -> 9.35% ECM jammer strength : 0.28 strength
| |
| | |
| So in total we will have 4.18 jammer strength (uh oh)
| |
| | |
| Chance to jam = (4.18 / 22) * 100%
| |
| | |
| Chance to jam = ~ 19%
| |
| | |
| So you have a small chance to survive and you will probably be turned into goo! Oh well.. for the fun of it let us work out the chance of the NON-racial jammers on him (hey, every little bit helps right?)
| |
| | |
| Lets assume you have 1 of each racial jammer. Their jamming strength when miss matched with the target is 1. With our modifiers that gives us a strength of 1.39 jamming strength
| |
| | |
| Chance to jam = (1.39/22) * 100%
| |
| | |
| Chance to jam = ~ 6%
| |
| | |
| If you activate all you get ~32% (please check my maths)
| |
| | |
| So that is pretty bad, but it is still something!
| |
| | |
| === Scenario 2 ===
| |
| | |
| Now lets assume we run into the same Raven but this time we are rolling with 4 Multispectral jammers. We get him targeted and we throw all of our jammers at once.
| |
| | |
| Ok, the Meta 1 Multispectral has a jammer strength of: 2
| |
| With all of our bonuses the strength comes up to: 2.78
| |
| | |
| Chance to Jam = (1 -(1 - 2.78 / 22 ) ^ 4)*100%
| |
| | |
| Chance to Jam = ~ 42%
| |
| | |
| or ~13% per module
| |
| | |
| Ok this is a little better...
| |
| | |
| === Scenario 3 ===
| |
| | |
| Ok now let's assume we were going to hunt a known target, a Raven! We are so sure this is the only thing we will run into that we put 4 racial jammers on our Blackbird and let out an evil giggle.
| |
| | |
| We found above that using a racial jammer gives us a gravimetric strength of 4.18 (per module)
| |
| | |
| Chance to Jam = (1 -(1 - 4.18 / 22 ) ^ 4)*100%
| |
| | |
| Chance to Jam = ~ 57%
| |
| | |
| So you can see you have an advantage when you know your target type and fit appropriately. But this advantage isn't that great and most of the time you can fit rainbow (one of each racial) or multispectrals.
| |
| | |
| === Scenario 4 ===
| |
| | |
| Ok let's assume you have a little bit of money and can afford to use Meta 4 jamming modules (BZ-5 Neutralizing Spatial Destablizer ECM) and you can fit two Medium Particle Dispersion Augmentors. Let's also assume that you have spent ~5-6 days training up Caldari Cruiser skill to IV and you have spent 2 weeks training Signal Dispersion to level 4 (requires CPU Management 5 and Electronic Warfare. This may take 2-3 weeks to acquire).
| |
| | |
| let's assume you fit a rainbow fit (one of each racial jammer) and you came up against the same Raven.
| |
| | |
| Your new shiny racial jammer has a base strength of 3.6 (not that much better than meta 0)
| |
| | |
| *Caldari Cruiser IV -> 60% (and 40% range)
| |
| *Signal Dispersion IV -> 20%
| |
| *Signal Distortion Amplifier II x 2 -> 18.7%
| |
| *Medium Particle Dispersion Augmentor x2 -> 18.7% (10% for first, 8.7% for second)
| |
| | |
| This leads to a large 8.98 strength jam. (using EFT to find this number)
| |
| | |
| Chance to jam = ( 8.98 / 22 ) * 100% = 40% with a single module
| |
| | |
| You can do the maths to work out how well 4x multispecs would work in this setup.
