Notice that Brewpastor used a batch size of 5.75gal not 5.0 gal which is where your efficiency numbers are wrong.
Second try setting your bitterness formula to Rager in the options under the tools menu. This gets me closer to Brewpastor but still not quite there. If I use Tinseth or Garetz I get around 50 IBUs for the same recipe.
