Est OG too high

[kevinlemme]

I am new to Beersmith but have been using Beer Alchemy for the last year.  I have heard good reviews regarding BS so I wanted to try it out.  I have updated my system profile for a brew sculpture with 70% eff.  I have put in two recipes from Brewing Classic Styles and it shows a higher than predicted OG.  Beer Alchemy is within a point or two on all the recipes from the book that I have worked on.  What have I done incorrectly in my setup?  Any suggestions?

Thanks,
Kevin

Kevin-

Can you post an example of your equipment profile and a recipe?

At work, will plan on doing this tonight.  Thanks for the help!

batch sizes? trub loss?

Remember that beersmith batch size is the volume INTO the fermenter. 
I don't know what the Beer Alchemy definition of batch size is. 
I don't know the BCS batch size, but normally JZ targets 6 gallons post-boil, 1/2 gallon trub loss, 5.5 gallon into fermenter. 

I'm guessing somewhere in there is the cause of the difference.

After putting your suggestions into BS, I am much closer.  I will continue to tweak the numbers with my system.  Thanks for your help and sorry for the tardy reply!
