I have the option of either discarding it, or massively speeding it up. I have reason to believe that large speed increases are feasible (similar models exist and have been used for sensitivity analyses in the literature).

Why would it be an oxymoron? I said the model is elegant, I didn't say my code is elegant. Quite a strange comment to make.
