I was overgating 40kt ships over 600 lys using inf/300 gates.
I ended up losing ships, despite the calculator saying it's perfectly safe..

Any idea what's going on?
Is the stars calculator incorrect here?

Hmm...were the ships already very damaged? The calculator shows that they would take 25% damage from that trip.

What we need's a few good taters.

nope, no damage to any of them. They were already fully healed ships.

The calculator shows 99% damage at 1499ly and 100% at 1500ly, which matches expectations.

Either this is a bug, or there's an error in what you've stated.

Only one gate on each base, I assume.

Wild guess: did you upgrade one or the other gate during the same year as moving? I've never noticed that being a problem, but perhaps this is an edge case. Even at that, with 100/250 gates you should only take 34% damage, with no losses.

You sure your ships aren't *400* kt? Rolling Eyes

I created a testbed.

Made two IT colonies (1249 LYs apart from each other) and put solo inf/300 gate stations.

The Non IT race, built 10 39kt scouts.
They moved to 1st IT planet with 0% damage.
It then gated 1249 lys from one IT gate to the other IT gate.

The Stars Calc says that it will take 79% damage, with no losses.

However, in the game I lost 4 ships and ended with damage of 6 @ 78% ...

I've just done a testbed as well and I get the same thing.

500 scouts, 39kt, built by non-IT race, traveling 1250.67 ly from an inf/300 gate to an inf/300 gate. Both planets owned by IT race with the non-IT set to friend.

143 scouts died.
357 survived, with 75% damage.

Second trial, with 500 new scouts, making the same trip in the opposite direction:
136 scouts died.
364 survived, with @75% damage.

I think it's a little different then you think. I think it's more like.

1. the IT gating advantage is a race trait, so other races using a IT gate do not get it.

2. In the Calculator it gives you 'amount of damage' and the 'chance of the fleet disappearing' from overgating.

3. If the fleet does not disappear then it get's damaged.

4. If the damage is enough then some ships in the fleet are destroyed.

5. It appears that overgating damage is random, in that sometimes you can overgate without damage and sometimes you can loose ships within a fleet and the remaining ships are undamaged.

Posey's calculator states 79% damage + 26% losses.

This matches the data well.

StarsCal 3.06 doesn't seem to give any chance of loss for non-IT races and predicts 79% damage.

Conclusion. StarsCal 3.06 doesn't work properly.

Well, the damage is close enough that I'd call it correct, the 1% difference is probably due to the usual rounding errors.

Here some info from experience:
1) ITs never loose ships.
The only exception is due to accumulated damage of 100% or more.

2) Mass-overgating leads to losses.
The not exact formula was once posted in the Advanced Stars! FAQ.

3) Distance-overgating leads to losses as well.
There are several posts, including the FAQ, stating that only distance-overgating leads to losses but that's wrong... at least nowadays. It could be that it was changed in the later Stars versions or patches. Most of the articles and calculations about gates are rather old and thus might refer to older versions.

4) Damage calculations due to mass- or distance-overgating are the same for every PRT including ITs.

Could it be that StarsCal doesnt perform a distance overgate loss check for the IT-only gates?

Checked that at same time (i.e. with both 300/500 gates etc) before coming to the conclusion it doesn't give %loss for non-IT

I don't think this is accurate.

Twice, I gated 500 39kt scouts 1250.67ly as a non-IT race through IT gates (inf/300 on both ends). I gated them as 500 separate fleets. Each time, each ship had 75% damage. There was no random variation in amount of damage.

I just downloaded Posey's sheet (version 2.20) and put in the parameters.
Sending gate: 2
Receiving gate: 2
Max mass in fleet: 39
Distance: 1250

The calculator says 79% damage and 0% losses.

What am I missing?

I have version 2.32d and it says 79% loss and in the box below 26% chance of loss.

Score one for version numbering.

Where can I download the newer version? I got mine from the downloads page on the wiki.

Or could you email it to me? My user name at gmail. Very Happy

There is not supposed to be a variation in the amount of damage. The only practical difference is that IT races never ever lose ships to the void while non-IT races have a chance to lose ships to the void.

Chances to lose ships to the void increase exponentially both for over distances and over weight and of course increase as you increase distance and weight over the "safe" limits. This mean that you have a way higher chance of losing ships if you go over both and minimize risk by going over only one of those two factors.

IT races only have to bother with damage. And there is always the possibility to use the repair after gating trick if you have an SFX or another fleet at destination.

Got confused by the quote Eagle used before I figured out that Eagle was talking about the quote before the quote...
the one that spoke that damage is variable.

Hmmm. I agree, damage is never variable in my experience, if the distances are known.
It was the ships lost to the void that was the surprise.

Just to clarify that.

If an IT gets a 501kT ship and gates it through a 100/250 gate over 3-400 ly...

Is the damage limited to 99% or will it die?

I think it will at least fail to gate as it would be >5x the gate size.

A 499kT ship?

IT will lose ships that reach 100% damage.
A fresh 501kt ship through a 100/250 gate will take 100% damage and die.
A fresh 499kt ship through a 100/250 gate will take 99% damage but will not die.
A 499kt ship which already has 1% damage sent through a 100/250 gate will take 99% damage and die.
IT will *not* lose ships to "the void" like other races do when overgating. Non-IT races have a % chance of loss when overgating. That % chance does not apply to IT.

Thanks - thought that was the case, but there were "if anyone knows this percentage for IT" queries on a couple of articles which threw me.

You can gate only ships up to 500kt. Fresh 501kt ship WILL not be gated. Player trying to gate such ships will get message from system:

XXXXX# attempted to use the stargate at XXXXX to reach XXXXX but could not because ships of type XXXXX were too massive.

For my IT experience(and few tests) - anything between 496-500 will die - even if race that gating ships is IT.
Below 495kt and less - 98% damage, but save for IT. I rarely seened 99% on overgated ship - it is either 98%....or you dont see any overgated ships at all.
