Fellow Industrialists,
We ran across what appears to be a gap in the knowledge of EVE production and wanted to document our findings for others.
In T2 production, the job cost of inventing a T2 blueprint is based on the Estimated Item Value (EIV) for the blueprint copy (BPC) being invented. As has been previously documented, the EIV can be computed based on the ME0 materials for the blueprint copy being invented and the Adjusted Prices (computed by CCP secret magic and available from the API) for those materials. So far so good.
However, for T3 production we couldn’t find any reference for how Estimated Item Value (EIV) for the invention job cost calculation is computed for Ancient Relic invention. Because relics can’t be directly manufactured, there isn’t a directly equivalent way to compute the EIV as is possible with blueprint copies for T2 invention.
After doing some experiments, we discovered the EIV for invention jobs on relics appears to be computed based on the invented blueprint rather than the relic. This might seem problematic because each hull or subsystem relic can invent multiple different T3 blueprints, however, the materials are the same for producing any T3 blueprint selected from a given relic.
For example (computed on 31-10-2017):
- If we pull up an invention job on a “Wrecked Hull Section”, the job window says 2% of the EIV is 2,473,090 ISK
- Thus, the EIV is 123,654,499 ISK
- Computing the EIV of the Tengu Blueprint, Legion Blueprint, Proteus Blueprint, and Loki Blueprint ourselves we get 123,654,490.82 ISK
- Thus, it appears the invention EIV was based on the EIV of the output blueprint
This math appears to work on subsystems in addition to hulls (as of 10-31-2017).
