Hi All,

I'm just getting myself into invention and I have a question. I'm not sure if this is a noob question or not, but I've had a quick search on Google and can't find anything definitive on the subject.

When using BPC's for invention, what effect does using max run BPC's have on the outcome? For example, which is more efficient:

A random example, a Merlin BPC:
Using a 1 run BPC
Using a 10 run BPC
Using a 30 run BPC (Max runs)

It is obviously much faster to use 1 run BPC's but there must be a downside to doing this? For time efficiency, does using somewhere in the middle (Say, 15 run BPC using the above example) work?

Thanks in advance - and apologies if this has been asked 1410923470 times....

It depends on what we are inventing:

A T1 BPC for a Drone Damage Amplifier I will may have anywhere between 1-300 runs on it.
An invented T2 BPC for the Drone Damage Amplifier II will have anywhere from 1-10 runs on it***

If you invented the T2 item BPC using a max run t1 item BPC, you end up with the max runs on the T2 BPC (== 10).
If you invented the T2 item BPC using a 1/2 of max run t1 item BPC (150 runs), you end up with only half the max runs on the T2 BPC (== 5).
If you invented the T2 item BPC using a 1 run BPC, you end up with a run 1 T2 BPC.

Now, different types of items have different "max runs". Generally speaking, the max runs you can get on:
a t2 module == 10.
a T2 Ship == 1.
a T2 Ammo == 5000 for normal charges, 4 for laser crystals, and 1 for mining crystals.

There is another aspect you need to consider though. Decryptors. Decryptors have the ability to change the number of runs on an invented BPC (as well as invention probability, ME, and PE levels). To actually receive the +x Runs benefit from the decryptor, you need to be using a max run BPC, with the exception of ships.

Since invented t2 ship bpc's only create 1 run, and you don't have to use a max run bpc to utilize decrytpors, you should only use 1-run Merlin BPC's when inventing Hawks and Harpies.

*** A T2 BPC for the Drone Damage Amplifier II may actually have up to 100 runs per BPC copy, but only if someone uses a T2 BPO to create the BPC, which doesn't exist for this module, not to mention a T2 BPO holder would rarely make copies when they can simply manufacture the item in less time. When inventing, the "max runs" on an invented t2 BPC, when not utilizing decryptors, will be 10% of the "max runs per BPC" attribute if showing info on the T2 BPO.

*edit* Read this guide: http://eve-prosper.blogspot.com/2013/07/everything-you-never-wanted-to-know.html

A non-max run T1 BPC will make a non-max run T2 BPC.

Increasing the amount of runs on Ship and Rig BPC's does not give you any more runs when inventing. It just makes the process take more time.

There's no reason to use more than a 1 run copy if you are inventing ships and/or rigs.

I haven't done ship invention since pre-odyssey, can you now get invented t2 bpcs that have multiple runs on ships?

OP yeah, Krixtal is incorrect. There is no need to use a max run BPC for ship invention. Modules yes, ships no. It really depends on the run stats for the BPC and the formula for end runs for each particular bp.

Check the program in my signature for comparing different invention variables and profit.

I am a victim of the "change". Sorry.

I hate how CCP just randomly changes things anymore. Been playing over 4 years and sometimes I feel like I have no idea what's really going on. Is that really a good idea in their minds ???? Yup.
