EVE General Discussion

Nice video.

I've always worked on the basis that if the cycle time of your AB is shorter than your align time, it's worth doing; otherwise it's better to align without a prop module active.

Reason being, time to warp is dependent on mass:

TimeToWarp = -ln(0.25) × Mass_kg × Agility / 1000000

(from the wiki)

So if you activate an AB, the mass of your ship will increase and that will increase the time to warp (assuming you don't turn the AB off).

So if you will warp normally, faster than 1 cycle of the AB, don't use the AB.

If your time to warp is slower than 1 cycle of the AB, then it's worth considering, though I personally prefer MWD/Cloak wherever possible.

Also, the kick back you mention at the end of the video is a result of the mass change in your ship, increasing the align time. It's not actually a slowing of your ship at all, which is still accelerating. It's matched at the other end of your cycle where you instawarp because once the mass drops again, the calculation determines that you should be in warp already even though you are still accelerating the update before the AB switches off.

Of course, I could be totally wrong on all that because I suck at Eve and really just wing it most of the time.

Just be wary about using AB for MWD cloak. The acceleration curve for AB is worse than an MWD, you may not attain the necessary speed to warp < 7.5secs (@max AB skill).

Mathematically, yes.

Guido van Rossum (inventor of Python) once wrote, code is read much more often than it is written, so readability is important.

In terms of being tied into reaching 75% of max speed when aligning to warp, -ln(0.25) is clearer than ln(4).

We should also not use the word "agility". There is no such attribute in the game. What is meant by that is "inertia modifier".

Clearly not of course. Otherwise that's the way it would have been done.

But of course, mathematically 0.25 is the same as 1000 - 999.75, so you know, could have just gone with that for example.

He seems to be implying that there are many ways of arriving at 0.25, and that this would somehow be a reason not to include the percentage calculation that determines how long it takes to reach a given speed.


As for the OP, yes, old trick. It used to be really worthless with an AB but the change in how the skill works means it's now also an option for fiddling with the speed thresholds. As others have pointed out, though, just make sure you can actually accelerate to the required speed in one cycle, or you're better off fitting an MWD or just not using the AB at all.

The reason is because it's the same as -ln(1-0.75). As in “you have to reach 75% (0.75) of top speed.”
Writing it as 0.25 is just a shorthand that obfuscates why you arrive at that multiplier. It's not something CCP has chosen; it's just the outcome of the equation given the exact speed we're talking about.

The whole -ln(x) part of the equation is the generic function used to determine how long it takes to reach any given speed. It is part of the general equation for acceleration, which states that t(v) = I×M×10⁶×(-ln(1-v/vmax)) — v/vmax is just a way of saying “percentage of top speed”. Since warping happens at a fixed percentage (75%), we can simplify that last bit as saying -ln(1-0.75), which, if you don't care about the whys can be further simplified as -ln(0.25).

So Cristl is entirely correct: if anything, it should be written as -ln(1-0.75), since that's the constant we want to use. -ln(0.25) is acceptable, but not as readable since it skips important information. Hell, even rewriting it as ln(n) works, but it becomes really cumbersome at that point: now you're measuring “n:ths left 'till max speed” — at 75%, you have ¼ of max speed to go (n=4), which means we can write it as ln(4).

Thanks. I wasn't trying to be being wanky when I made my earlier comments.

Whatever, let's let it go. Beers all around.

Yes, there are a lot of angry basement dwelling neckbeard blowhards in this game who completely lack any form of social skills beyond "bite me".

As for OP, yes the AB can be better than MWD in some cases, but be certain to test run it to verify assumptions. Each Char will have a different experience depending on skills, fitting, and base hull.

I still don't get it. What is "In"?

Can somebody make an align time calculation for an orca for example please?
