The nuance here is if you're making a decision that has a gross positive value, then you likely have a large number of "wrongness" choices that still result in a net positive. If you're not sure which of them to take then take any one that has a positive EROI (the ambiguity makes them all appear similar returns). Remember that EROI is marginal so even if you end up in a lossy situation _after_ the decision, so long as it's less loss than before you're net better off than you were.
If you're making a decision which all decisions seem to have a net negative EROI, then there is no opportunity at hand. Keep looking for a real opportunity.
