This never even occured to me....
Must say though coincidentally, my IBU was in the 50's (according to BeerSmith) while my OG was also in the 50's. Will definately keep this bit of info in mind the next time I make a stout
Thanks
You should be fine then.
You should check out Ray Daniels' book 'Designing Great Beers', Its full of info like that plus guidelines for brewing most beer styles. It's the best homebrewing book I own.
Like andybrock pointed out, hop utilisation varies from set-up to set-up, so IBUs are very subjective.
