I am not that lazy. Just found it in one particular site, whose address i can't give (due to forum rules, not by some evil intent). It's an interesting reading, though. I can translate it, if anybody shows interest. And if it's not outlawed to post comments, based on reverse engineering of the game (pjknibbs, any advice?).
I can't believe it! Using the kotekzot's info i've just capped 5 out of 16, including an Eclipse and LX! Well, probably it was a coincidence, but still a pleasant one.
It seems, that the weapon of choice has little importance, after all (as long as it's not an ID). You just have to attack ferociously and quickly finish the whole affair.
ULiX is the one who reverse engineered the game's mechanics relevant to ship capture, as well as the ware dropping, assasination mission ship generation and the rating chaging, i just read and understood them. here's the relevant procedure.

I really don't have a problem, just can't understand that as advice for capping ships.
For 'malky', read 'just keep plugging away at the enemy'. I've never managed to cap a ship by holding back from trying to destroy it. Only exception might be transport ships, and even then, only if they're honest traders, which seems kinda 'yarr, I be taking yer gold, and yer ship, yarrr...'

Neither do I. In my opinion, it's too tantric way to enjoy a dogfight
On the contrary, it's more likely to capture a ship, if you hit it hard in the very beginning.
does the start you choose affect you many caps you get? because i have a terrible cap rate on my quick start profile, but in the short time i played the bankrupt assassin, i capped about 20 ships, and that was in about 30 mins, and ive used the same setup on my quick start account, with same fighting rank, and higher, and still have a terrible cap rate.
if Ion Disruptor is used [probably for capping], then the probability is at 0.04 %
87% is maximum allowed
time (age) of game must be greater than '[next] take over' time
...
IF player 'age' > 'next chance'[to capture]
if 'delay between captures' larger than 300 seconds
and
player 'age' > 'next chance' + 'delay between captures'
then change delay between captures' to 30 seconds
else
'delay between captures' = 'delay between captures' * 2
'next chance'[to capture] = player 'age' + 'delay between captures'
...
initial probability = 30 - morale
if attacker strength(shield+hull+max laser damage) < victim strength(shield+hull+max laser damage)
probability -= 5
if hull is not zero
a little bit added to the probability based on current hull damage
+1% with hull less than 25%
+2% with hull less than 2%
+3% with hull less than 8%
+10% with hull less than 2%
probability decreased over period of time. i.e. gets worse with 'next chance'[to capture] by around 1%, 2%, 4%, 8%, 16% for 30, 60, 120, 240, 480 seconds
if race is Khaak, then the fighting rank is checked
can only capture like any other ship, when above "30"
not possible to do before "6"
at the end,
if the current probability > random number from 0 to 99
then we CAPTURE
______________________________
lets try to summarize
ok, so ID is BAD to use,
not sure in what case: after the shields are dropped, or at all?
I assume the first one.
87% is maximum possible Hull on captured ship - we knew that.
Capping chance is NOT calculated per every hit, as previously thought, instead it follow intervals: 30 seconds, 60, 120, 240, 480, then apparently 30 again, and so on.
The growing intervals slightly decrease your chances by 1%, 2%, 4%, 8%, 16%. Then apparently revert back to 1% when the interval reverts back to 30 seconds.
Which means we want to cap right away, or only some time (30 seconds) later. Not quite sure if the cap is calculated on the very first hit, the initial values arent given there.
initial probability = 30 - morale
so the previously made assumption that moral makes a difference, is correct. The smaller - the better.
Ship make a difference, apparently. Hulls, Shields and max laser are all taken into account on both ships.
If you are "weaker" than the ship you are trying to capture it will decrease your chances by 5%.
I assume the laser is the attacking laser, not all lasers equipped.
if race is Khaak, then the Combat Rank is checked
can only capture like any other ship, when above "30"
not possible to do before "6"
Anyone knows what ranks those numbers correspond to?
at the end, the probability is (obviously) tried against a random number
so to summarize the summary
probability to cap with Ion Disruptor is less than 4%
morale is the key, but as far as I know, you cant really check it without enabling script editor. One can guess maybe the ships that are ready to drop freight have low morale.
it seems like you may as well hit with strong lasers, while that's gonna kill the hull, it'll give you extra 5%.
more damage to the hull will also bump up your chances
big ships add to the difference, so for example, flying M6 is better than M3
Khaak captures are checked against Combat Rank
phew..... what did I miss?

Something is wrong with that analysis somewhere--it's easily possible to capture a ship without having to blast away at it for 30 seconds, which you seem to think is the case.
But in that case you'd pretty much only ever get bails when the hull is at 87% if you use PBEs like I do (their hull damage is very slow), and that simply isn't the case, believe me.
pjknibbs wrote:Something is wrong with that analysis somewhere--it's easily possible to capture a ship without having to blast away at it for 30 seconds, which you seem to think is the case.
The impression I got from the summary was that you have a certain % chance to cap at 87%, then another, slightly smaller chance to cap when you next hit them for hull damage after 30 seconds, then 60, then...
The end result? If you don't cap the first time you get them under 80%, fly away, come back after 30 seconds and try it again... if not then, then pop them, loot anything they leave behind, and move on?
Wonder what affects morale. I would assume that hurting them a LOT really quickly would affect it. Perhaps that offsets the IonDs adjustment -- since they hurt shields a LOT, really quickly, the adjustment is there to offset the huge morale penalty that they take?
