But at 1 over, or even break even, you're in better shape. You have to be willing to play a little fast and loose with Jim to actually use his ability. Defiance just makes that even better. You stand even better odds of succeeding at 1 over, which with Jim you should be doing anyways.
To answer your question: with anyone else at 1 over, Defiance gives you ~53% chance of success. So yes, it's better with Jim in that regard.
Sorry, that's not quite what I was asking.
What's the difference between using Defiance on the test, and not using Defiance on the test? Because that seems to be the important question here, and it seems like the answer should be the same for any investigator. Defiance will change some number of tokens from "fail" to "pass", and that'll be the same for any investigator at the same over/under.
