BPC and Invention Mechanics

[Nardieu_Gaterau]

So I recently did some research online, created an industry alt, purchased bco’s, copied them and did some invention.

I expected the following during the invention process (as an example): make a ten run tech I bpc, invent one run and, if successful, out pops a 10 run tech 2 bpc and 9 runs are left in the tech 1 bpc.

Instead what I get is a one to one ratio (if the invention process is successful), a one run tech 2 bpc and a tech 1 bpc with one less run.

I did some reading before starting the industry alt. Everything I read with a recent date on it said a 1 to 10 ratio not 1 to 1. Did the mechanics of this change recently or am I missing something?

In general, if you invent modules, drones or ammo, you will get a 10 run bpc. If you invent ships or rigs, you get a 1 run bpc. In each case the process will consume 1 run of the T1 bpc. The industry tool will show you the number of runs and the probability of success.

When inventing ships or rigs, it is generally beneficial to use a decryptor to increase the number of runs and/or the probability of success. My preference is a parity decryptor.

Decryptor cost needs to be balanced against the datacore cost of the same number of runs without the decryptor.

Been a while since i did anything but t2 ships and rigs used to be 1 run bpcs and modules 10runs.
When you use t1 bpc to invent, it loses one run.

Aaahhhhh that explains alot. I missed the rig part in my reading. I thought the 1 to 1 only applied to ships.

The item in question is a rig.

Thanks.

you will have to do some math to figure out what the best decryptor to use is, each one changes the probability of success, number of runs, me and te of the finished blueprint. For some jobs you want to max the number of runs, others the ME, others the probability, and then for some jobs you might decide none of those matter and you want to max something else.
