Edited by: Fink Angel on 08/04/2008 21:13:54 Just a quick one ...
Is the relationship between signature radius of a target and sensor strength / locktime linear or a curve of some sort?
Has anyone reverse engineered a formula?
Edit: Erm, this might not be the right forum for this, but doesn't seem too right for "general", nor anywhere else really.

It's apparently this, c/o Blazde:
Quote: The most accurate lock time formula I know of is:
seconds = ((40000 / ScanRes) / (asinh(SigRadius) ^ 2))
Which I derived after testing the very long lock times on EW starbase mods (10mm scan res) before they got boosted back up. It also fits short lock times perfectly.
I haven't tested this myself, but it was backed up by another person who'd been trying to come up with the formula independently. * * * In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

Although it may be right, there is lag you must also account for. I have seen it take a minute to lock a battleship in a mission with a battlecruiser. Normally, I get an additional 1/2 second lag in most systems.

Great stuff. Thanks for the information.
It's not really for my lock times. I just bought some Halo implants (low-grade, I'm not too rich!) and wanted to see in reality how much difference the sig reduction would make in someone locking me.
TBH I'm not 100% sure whether the primary point of Halos is to take less damage from missiles / make guns harder to hit you / take a longer time to lock you.

Locing formula:
T = (40000/X)/(asinh(Y)^2)
Where: X = scan resolution of your ship Y = sig radius of the target T = the time to lock. |

I got a Halo set recently as well.
I needed some +2s so I figured I might as well fork the 40M and get a added bonus which is relatively nice on small ships, just got careful now about getting my pod out (I used +1s previously, so I didn't really care much).
Well, you take a bit longer to get locked but the difference isn't very big (naturally, every bit counts) - the decrease in DPS from missiles due to explosion radius is noticeable.
Guns much less so if you're webbed, as sig radius does very little (impacts hit quality a slight bit from what I hear) without factoring it into transversal.
The difference in lock-time is rather marginal: a Rupture with Sig Analysis V takes 7.4s to lock a Wolf. A Wolf with Halos takes about 7.9s to lock. Obviously, every bit helps in such a unmaneuverable ship, but if avoiding getting locked is your goal, you'd be better off with something for agility.

Thanks again. No wonder Halos are relatively cheap. I was hoping people's locktimes on me would be prolonged fairly reasonably. Doh! |

Well, they happen to have a smaller bonus then any other pirate implant set, which doesn't help either.
The most useful part of the Halo set (well, aside the slight locktime/tracking effects) is reduced missile damage, there is a actually noticeable damage reduction when people fire missiles at you.
The tracking effects would be more significant if you weren't webbed in any small ships - but could be rather useful for a ceptor pilot who can't afford snakes.
I still like them, every split second and bit of reduced damage counts, and they're very cheap, particularly if you are smart and get your pod out.

To further answer the OP's question, your actual sensor strength has nothing to do with your lock time or how long it takes to lock you; it is simply how resistant you are to ECM.
Your sensor strength does factor into how easy you are to scan down with scan probes though. I don't recall the exact relationship, but the higher your sensor strength the harder you are to scan down. So, in theory at least, if you wanted to be hard to find without cloaking you could fit a few ECCM modules. Please note that I have never tried this nor do I know anyone else who has so I have no idea how much of an actual impact it has. -------------------- "I am hard pressed on my right; my centre is giving way; situation excellent; I am attacking." - Ferdinand Foch at the Battle of the Marne |

Sorry man, meant to say "scan resolution".

It does work, and the effect is fairly substantial. Whether ECCM / SBA are worth the module slots if you're expecting to need them for their anti-jamming benefits too is harder to say.
Reducing your sigradius will help in the same way, but Halo's aren't very impressive for it. * * * In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

I doubt anyone would expect a formula to account for lag. Unless it was something like locktime + lag = sux. * * * In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

Wow, I'm a nerd.
I just programmed this into my TI-89 calculator as a function.
So you put in
eve/locktime(50, 100) for instance, and it'll give you the lock time.
