Thanks Chris for the above. (Wandered off track last night so I got rid of my irrelevant posts

)
I think Brad is thinking on how to give the user an option to work off either 'Mash Efficiency' or 'Brewhouse Efficiency'. I'd love this as I spend a lot of time converting recipes and find 'end of boil' the easiest common ground to work from. (Most recipes on the net are really hard to convert to your equipment as the provider rarely gives enough information or uses ambiguous terminology such as 'Batch Size' and 'Efficiency' which are terms that mean different things to different brewers unfortunately.)
If he is able to do this, I think this would make things much easier. While the calcs are correct in BeerSmith2, it is quite easy to make an error. eg Change 'Loss to Trub and Chiller' and then forget to adjust your 'Brewhouse Efficiency' accordingly and your OGs etc will be incorrect. I still sometimes forget

. And it
is difficult to work out how much to adjust it by. Setting 'Loss to Trub and Chiller' to zero and then making 'Batch Size' your end of boil volume is what many people, like you and me, currently find simpler.
If you were able to 'lock in' your 'Mash Efficiency' in BeerSmith, I think that would solve all your worries. Do you reckon it would? (I couldn't quite follow some of your figures above but I think I got the general idea

)
Cheers,
Pat
P.S. On the sharing of recipes, use either the 'Classic Recipe' report or the 'Plain Text' one as they include, 'End of Boil Volume,' 'Batch Size (fermenter)', 'Brewhouse Efficiency' and 'Mash Efficiency' which makes interpretation much easier.
