I’m currently working on an application for tracking industry profits, and I’ve run into an issue when determining what decryptors were used for invention.
I don’t see anything in the ESI API that actually says directly which one, or any, were used. I think you could work it out given the character’s current skills and the probability value, which is provided. However, to do this correctly I’d need to know the character’s skills at the time the job was submitted, which means I’d need to keep snapshots or a timeline of when those skill levels changed. Given that information, I think you can use the SDE to determine the probability for each decryptor and therefore solve for which one was used.
Is there something I’m missing here or is that the only way?
