Hi,
I would like to hear peoples comments on ECM jamming and the formula that has been thrown around to calculate the % chance of a jam (From:http://oldforums.eveonline.com/?a=topic&threadID=511720&page=8)
If the sensor strength of the ship is less than your jam strength, then it seems to calculate strange results.
So, if the ship sensor strength is equal or less then your jam strength, does that mean the your chance of jam is 100%?
Judging from that formula, I can only presume so. But I'm sure I've seen posts saying that its still 'chanced' based and you cant get 100% jam chance.
This is particularly relevant when you have high skills and use racial jammers, as strengths of 12+ are achievable, which is more than some ships. This is based on using a single jammer, and not multiple ones.
As an example, the Arbitrator has a sensor strength of 12, and a sigle amarr jammer can have over 12 strength (14 I think on max), so in theory this ship should be jammed 100% of the time.
Any comments are welcome.
Thanks,
Rob.

By "chance based" they are referring to the ratio of Jamming Strength to Sensor Strength.
Unless CCP uses an additional variable that influences the 'chance' of jamming, a jammer with a strength above the sensor strength of a ship will always give a successful jam.
If you really want to test this, grab a friend (or 7) and fire up your jammers....try jamming at least 100+ times... Who knows...maybe CCP put in a few percent chance that a jam will fail?

jamming chance per jammer is jammer strength/ship strength*100

Jam strength vs sensor strength
Jam strength = 14 vs Sensor srength = 28
this gives you a 50% chance of jamming. But...
2 x Jam strength = 14 vs Sensor strngth = 28
this gives you 2 x 50% chances of jamming. This means...
you may perma jam a crrier, or you may fail to jam an inty. The only certanty is that if your jam strength is over the sensor strength of the opponant, then you are garuntered a jam

More accurately...
Using 2x jammers with a strength of 14 ( ) against a target with a sensor strength of 28, means you have a 75% chance of jamming that ship each cycle (using both jammers).
(1-(1-14/28)^2)*100% = 75%
All interceptors have a sensor strength less than 14. Assuming no ECCM is used, you will jam all ships with a sensor strength <= 14 every time if that ship is withing the jammer's optimal range.

It's true. I had to look at a maths text-book last time I wanted to work this out, but it's true.
