stealth? they said they were nerfing the spawn rate to combat the pirate battleship bpc drops

There is a big difference between item drop rate and npc spawn rate...

100 hours of dedicated ratting time is enough to indicate there's probably something is probably different. Before the patch, 100 hours meant 80-120 Sentient spawns. After the patch, we've gotten 12 total. Since I'm the dedicated looter, and my income depends on sentient/elite spawns, I went so far as to combat probe our system for over 6 hours, looking for people not reporting spawns. They aren't spawning... 100 is valid starting sample size. And by this point the rate should at least be creeping towards the mean, which it isn't. This new average is stable...

Maybe if you have 1,000 people with 100 hrs each. Don't you know how to Science? You need controls and multiple data points.

Sounds like you can't math. You want 11.4 years of data? LOL!

Since me and one other salvager track spawns and who gets them for our corp, so we can divvy it up fairly, i know we had 300 hours of data with an average of 4 people ratting 2 patrols or hordes per hour. The average Sentient per hour per site runner was around 0.2 with a 95% confidence.

The current average Sentient per hour per site runner is 0.075 and over 90% outside of the previous standard deviation. The new sample is 10% of data volume from last month.

The new sample meets the minimum standard forGÇï statistical significance.

Minimum standard doesn't actually imply statistical significance and all those tests are based on certain assumptions. Even before the changes you could go for weeks without anything and then get 3 factions spawns and escalations in one evening. Your numbers are tiny and so is their significance especially since you are dealing with a competent RNG and not some kind of balanced distribution algorithm that gives you cake after x amount of effort.

Incorrect. I'm consolidating data from many people. We're talking about 4 characters ratting each hour, each running 2 of the same type of sites per hour. That is 264 sites run since patch. I'm not talking about one person's experience of RNG. This is from 20 or so people. The sample size is sufficient.

Imbicil, when a not so random number (1-100) is multiplied by another number (spawn chance was around 15%), the results are not random. They are quite predictable, especially over a 2 day period window with over 300 points.

I thought eve players were supposed to be smarter than you dunces.

Math degree here.

This is statistically significant, but not proof beyond reasonable doubt.


Have you investigated for any systemic biases in your data gathering? Anything you might be doing differently post patch?

In June we are starting to address the supply of pirate battleship BPCs, with moderate changes to the chance of escalations spawning from the most popular high-end anomalies and larger changes to the drop rates of the BPCs themselves from quite a few NPCs.

Since the patch, there has been a drastic difference in the number of Rogue Drone Sentient spawns when doing combat sites. My corpmates and I are getting these spawns at least 1/5th to 1/10th as often, compared to before the patch. I don't make this claim lightly. Combined my corp has accumulated over 100 hours of data since the patch. Last month we ran over 1,000 Drone Patrols.

Is this intended?

When each ratter finishes a site, they make a corp BM (with their name-Time) on any Sentient wreck so that it can be looted while they move to the next site. While warping to the next site they add the BM name to our shared spreadsheet, with change tracking, so that us looters can't "forget" to log their BMs. They have been in the habit of making BMs for Sentients for over a month now. (And after the patch they are REALLY motivated to remember to BM them because they've noticed the lack of spawns.) Us looter/salvagers (work at home with personal monitor on Eve) collect the loot, verifying that the ratter isn't padding their numbers with false BMs, and make a portion of the profits.

Same system, same maxed out military index, similar enough ship setups that all make 40-60 mil per hour.

I have access to the API of the people ratting and have looked at their ratting ticks. Sentients give an extra 8-11mil in a single tick, and are pretty easy to find. Their ticks show that they are doing the same amount of work, but getting 1/5th (or worse) as many Sentient spawns.

Yesterday there was 3-4 ratters on at a time for 10 hours, and we didn't get a single Sentient. Last month our lowest Sentient count under the same circumstances is 4, going as high as 10, and we hit that scenario more than half of the days last month...


I would wager 5Bil that Rogue Drone Sentient spawns are considered escalations, or are some how affected by the patch changes (but CCP_Fozzie didn't know that they were connected in such a way). Seems that moderate means 20%, and the developer inverted the intended chance.
