Hello everone,
I know, as always, when playing with RNG, this might be just coincidence, but chances are at about 1000:1
Since the big "Retribution" patch, my invention-success dropped so low, one could call it "highly unlikely".
I tend to run a lot of inventions, and I happen to know binomial distribution, and, while calculating the probability of the results, it looks that the actual invention chance is at 0.4 now, where it should be 0.504 as all related skills are at V. This is a big difference!
Usually, invention results would even out, if taking a big enough sample, but since retribution, they wont do it anymore!
Is that a bug, a stealth nerf, or just plain bad luck in high amounts?! |

So, by "a lot" you mean like 10000 invention jobs, right? So... i started an industry blog at www.derbk.com/eve There i am preparing a guide to all things related to manufacturing. Check it out!

I think we need more data to know for sure. I know I could invent for a week and have really bad results, and then another week with good results. So just one week after Retribution I think is too soon to know exactly. I will be checking my own data a bit further ahead anyway bc for me at least a week is too soon.

How much data do you have? Also, in a group of 300k EVE players it is not that strange if one observes something one day with 1000:1 odds. |

I'd say the run of bad luck started before the patch hit!
But I'd also add that CCPs random number generator has been known to produce blocks of good or bad results for at least 7 years. So 10 to 100 bad results doesnt a stealth nerf make!
30ish years ago I ran a test on some "random number generators" & most required millions (and some 10s or 100s of millions) of results to show that they were random, not a handfull! |

Also, if I am to share my success rate, I have done close to 35,000 invention jobs. And I have a success rate of 47,58%
And since Retribution I actually have a 50% rate (altho haven't done many this week so that's not very accurate).

Well, then, it might be just plain bad luck.
Maybe I am just too used to predictable results, before Retribution, you could basically take any streak of ~200 inventions, and it would already even out and come pretty close to what it should be. I have been inventing for 3 or 4 years now, and I never encountered anything like that.

Quote:binomial distribution
Isn't binomial distribution a double peak?
Also what are you inventing. Im sure that success rates over time are related to itemss
You can have a long bad patch inventing warrior IIs compared to inventing Golums. As if you did not you would quickly go broke on the later. |

Uhhm, you don't sound like you know how invention works, for all things that are not ships, you can have exactly 50,4% chance with perfect skills and not decryptors.
And with "binomial distribution", I mean that I know how to use formualas like that to calculate probabilities. |
