Suppose you land at 2300m on the second tick, the server registers the jump request but notices that you’re now 3000m off the gate, so the jump doesn’t happen, and your freighter can look forward to a horrible death. Here’s the catch: Your client sends the jump command on the tick after you land, so if the BlOps is on the ball and bumps you on the first tick, the freighter immediately moves 700m or so away from the gate. Because your freighter is so massive, they have a good chance of landing a bump even accounting for the 3000m warp variance. Once they confirm that you’ve initiated warp, the station cloaky lights a covert cyno and bridges in a fast-moving Black Ops battleship, which then tries to align to the spot from which you will come out of warp. On popular LS-to-HS connections, they will wait with a cloaky ship near the gate with another cloaked scout on the station you’re undocking from. The chance of you landing in the death zone is the ratio between the surface areas of the death zone and warp variance sphere = 2πrh / 4πr2 = h/2rįor stations: 42% (a few high-alpha ships can use this opportunity to kill a hauler landing on a station)īut Twitchy, you say, what’s the danger here for jump freighter pilots? Well, low-sec pirates are well aware of this death zone creating a window of opportunity. The formula for the surface area of the death zone is simple = 2πrh Let h be the distance between the furthest possible point of the death zone and the docking/jumping range = 2500m for stations 500m for gates Surface area of the warp variance sphere = 4πr 2 Let r be the warp variance radius = 3000m The overlap of the warp variance sphere and the docking/jumping range (assumed here to be a plane, which is not quite exact but close enough) creates a spherical cap, which I will refer to going forward as the “death zone”. Ship model size does not impact warp variance (i.e., the radius of your ship does not bring you any closer to the gate after taking variance into account) The distribution of landing on the warp variance sphere is completely random, but always at a (more or less) 3000m distance

If warp variance causes you to land outside of the range, your ship starts moving towards the station (or gate) and initiates the dock (or jump) only once you are in rangeĪssumptions (to be validated, but I think are safe to make) “Warp to 0” means warping to the very edge of what is considered 0m of the thing you are warping to Warp variance is 3000m in a sphere around the point at which you warp to What do they have in common?Īnshar kill on a low-sec-to-high-sec connection Normally, folks don’t think twice about “Warp to 0” and jumping a gate or docking at a station, but what if I told you that, if you’re flying a slow ship, that this can be extraordinarily dangerous?

This means that, for a few seconds upon exiting the warp tunnel, you're still 'out of range' and vulnerable for a bump - thus, the warning about bumping and the recommendation for using insta-jump bookmarks is still valid. Now, this (combined with the above edit) is supposed to mean that you always land within the 2500m jump range, however, these bookmarks are taken after my ship exhausted its residual velocity from coming out of warp. You can see this visually on this potato GIF, where I repeatedly warped to the gate and bookmarked my landing position, then tried to manually pilot to the centre of all the bookmarks. This means that the centre of the sphere is 1250m from the gate. The edge of the warp variance sphere is 0m from the gate. Assuming a solid bump, the math changes to h/2r = (0m + 700m) / (2 * 2500m) = 14%ġ2-05: Edit 2 - To clarify, the centre of the warp variance sphere is NOT 0m from the gate. Warp variance does look to be 2500m, not 3000m. TL DR: Jump freighter pilots should use ‘insta-jump’ bookmarks on their lowsec-to-highsec connections, or risk getting bumped and murdered upon landing at the gate.ġ2-05: Edit - Based on some testing and additional data provided by u/guigui_lechat, it looks like CCP data might be wrong (typical not surprising).
