This assumes the temperature to be the same.

But I have been wrong before and I see no hope in changing that!

RI -- best of luck! Of course the best thing to do would be to duplicate the anticpated set-up and lighting conditions and do practice run. And who knows, the subject (and/or handlers) might be so impressed with the first shot (though the print will be too light and not impressive at all) that they'll grant you a couple more shots!
