Sampling Efficiently: A Guide to Reclaiming Thargoid Systems

So, as you (probably) know, Tissue Sampling in bulk is an incredibly efficient way to clear Thargoid-populated systems. But, how do you grab them in enough quantity quickly enough to make a difference? After many hours of trial, error and occasional explosion, I've managed to nail down a strategy that reliably produces me 180-200 samples per hour working alone. And in the interests of humanity, here's the result of my hard work!

THE SHIP:
The main idea is an Imperial Cutter with a fast-regenerating shield that can tank the Scout you'll be sampling and as many corrosion resistant cargo racks and research limpets as possible. With the ablility to launch 10 limpets at once and 80 slots for samples + 64 extra limpets/overflow space, it can gather a large amount of tissue samples quickly.
In terms of your own options, you'll want to choose Gimballed Enhanced AX Multi-Cannons, as they're the best way to clear Scouts. Additionally, a Caustic Sink can replace the Heat Sink if you've got access to one.
For players who lack engineering materials, the only critical parts that need unlocking/engineering are the shields and the CRCRs. Everything else can just be taken up to G2/3 or whatever is available.
EDIT: I have discovered that this Anaconda build Sampler Anaconda is significantly more efficient in terms of raw samples/hour. However, it is slower and more fragile if something goes wrong and you encounter more dangerous Thargoids, although this is fairly unlikely. The strategy to be used with it is the same.

THE STRATEGY:
Load up with a full hold of limpets and fly to the Control system you're trying to help clear. If you're hyperdicted by Interceptors on the way, just outrun them - if you're hyperdicted by a Glaive, you can just tank its fire until your drive finishes rebooting - it won't fire another missile until your drive is ready to engage, which is too late to stop you escaping. Alternatively, your multicannons should be able to kill it should you want to fight.
When you get there, drop into normal space and wait a few minutes for a "Frame Shift Anomaly Detected" warning and a ghost contact to appear on your radar. (Whilst you're waiting, go into Settings-Graphics-Display and set Frame Rate Cap to 30 FPS. Annoyingly, this is the only known way to mitigate a glitch that causes up to three-quarters of your limpets to return with no sample.) This contact is the Interceptor - you don't want it to notice you! Boost away until it disappears off your radar, then come to a stop again.
Wait another minute or two for a second anomaly warning. These are the Scouts you want to sample. Two of them will spawn - kill one, and launch all your research limpets at the other. Sit fairly still with 4 pips to SYS whilst the Scout flies around, firing more limpets whenever they come back.
Periodically, another pair of Scouts will spawn. Kill them with your AXMCs.
Continue sampling until you have filled your acceptable quota or ran out of limpets. You can only take as much as you have corrosive cargo racks if you want to avoid taking any damage, but if you're bold you can go beyond this - I regularly go up to 120+ samples with a very low risk to my thrusters, FSD or shields, but doing this has a high risk of breaking your cockpit canopy!
NOTE: Never only go a few samples beyond your safe limit. If your cargo hatch is damaged but not destroyed in one hit by module corrosion, you'll be at risk of the hatch malfunctioning and dropping some of your samples - and if that happens when you're flying back to the carrier, you can't pick them up and they're gone for good.

WHAT TO DO WITH THE SAMPLES:
You'll need to store or sell the samples to a fleet carrier in the general area, since it's not practical to try and move a sampling ship 80+LY to a rescue ship every run. This means that if you don't own one yourself, you'll need to join in with someone who does. The targets change as systems are recaptured and the Thursday updates happen, so check relevant forum threads or Discords to find out where other sampling groups are working - or just pick a weaker system and try to strike out on your own!

ANOTHER OPTION - AFK SAMPLING:
Tisssue sampling can be quite monotonous for some, so they may find it worthwhile to automate it. Although you can fairly easily deal with a single scout by means of using a rubber band or similar methods to hold down the trigger and fire research limpets, if you allow more Scouts to continue jumping in they will likely overwhelm your ship's shields and destroy you. So, using the normal method isn't an option - but, you can do this in AXCZs! Since Thargoids only drop into AXCZs around the main marker, a Scout lured 30-50km from the CZ can be safely sampled automatically without significant risk. Just leave your ship for half an hour each time to fill up!

Whilst the limpets do still fail sometimes, myself and everyone else who I’m aware of testing the FPS trick have got an 80-90% success rate whilst using it.
So, this makes a lot of sense, because historically tissue sampling success rates have been consistent on a per- commander basis... some would return typically 50-60%... myself and several others is are more like 20%, while some have said 80%. There might be local maxima and minima across that spectrum, but it usually converges on a per- commander value.

I thought it might be based on lag... but FPS is another vector. This will be an interesting vector to investigate.
 
The war information for HIP 25679 only shows destroy Thargoid craft, are you saying tissue sampling helps even though not stated?

Yes. It has been used extensively to clear many systems, and most of the progress currently on HIP 25679 is from samples.
 
im set at 30 fps and i get only 1 sample per interceptor :c
and you are sampling scouts only? is it worth it? id expect interceptors to make better progress...

“1 sample per interceptor”? What exactly do you mean by that?
EDIT: To address your other point - samples from Scouts and Interceptors give the same amount of progress, and it's generally easier to deal with Scouts.
EDIT 2: Wait - are you firing only one research limpet? You can attach multiple at a time.

multiple research limpets fired from multiple limpet controllers, multiple attach, multiple finish and multiple are retrieved. cargo: 1 tissue sample.
today i learned... :D

Hmm. Limpets can still fail sometimes even at 30FPS, and it appears partially related to the Thargoid's movement - if you fired them in a burst and they all launched at the same (wrong) time, that might be the problem. Was it just the one volley you tried?

Also, I find Scouts seem to give somewhat better success rates and give the same progress per sample - might be worth seeing if you have better luck with them.
 
i think i did try to get as many limpets in on a single interceptor, meaning multiple volleys, resulting in only 1 tissue anyway. but i will try some more and will look at the scouts for sure. thanks for the advice o7
 
Hmm,
I will give this a try tomorrow. Only doing Invasions at the moment and they soon run out (all defended usually in 2-3 days), leaving me to find other things to do.

I tried Tissue Samples a year or 2 ago and managed to get hundreds on my FC. Had no issues then, had over 80% success rate IIRC, had to kill all Scouts in NHSS until one left and then got Tissue Samples from it until limpets all gone.
Couldn't understand why everyone kept saying it didn't work - FD even cancelled CG for Samples due to stated 'bug'!
I think I even stated at the time that I got 4 out of 5 limpets returning with a sample and I RP'ed that said Scout was actively avoiding Limpets biting chunks out of it like a dog with fleas, scratching at them, etc.

EDIT never tried an Interceptor BTW.

Success rate for limpets varies greatly between players - some people only get about 25% of theirs returning samples. If you already have an 80% success rate, setting an FPS cap is probably optional.
 
One note worth making: An Anaconda is a better ship for this than the Cutter, as it has more internal slots (so you can add one more research limpet controller) and isn't gated behind a rep grind. Since you're only dealing with scouts, you don't need a hefty shield to tank interceptor shots.

I think you can only get one sample from an Orthrus, the other interceptor types allow you to get multiple. At least, I've only ever managed to get one from each Orthrus I encounter
 
Thank you for posting your experiences, OP!

Sorry, CMDRs. I'm a bit confused about this. Are you waiting to fire limpets (1 every few seconds, for example)? Are you firing them as fast as you can? Is 'a volley' as many from one controller that you can fire at time, then switch to another research controller and fire away all that it allows?

What's the issue here? Are limpets crashing into one another? Is the scout knocking them out? Is it losses due to random hits from enemy fire?
Thanks for clarifying!

As far as I can tell, sample losses are due to the limpets being glitched and sometimes impacting on the Thargoid’s hitbox as they launch. The rate at which this happens varies from player to player, and decreasing FPS helps.

And - as for firing research limpets, just bind them all to the same fire group and launch them until all the controllers are maxed. Firing a volley all at once can occasionally result in a large amount coming back with no samples if they launch at a bad moment, but it evens out overall since you’ll be using a lot of limpet volleys.
