When I set the mash temp of this recipe to 147, I get an estimated FG of 1.007.  When I lower the mash temp to 146, the estimated FG bumps up to 1.013.  I would expect the FG to go lower/drier at a lower mash temp.  Is this a bug or am I missing something?

I've had a similar problem going from a mash temp of 158F to 160F.  160F has a lower FG than 158F which is contrary to what I understand about mashing temps.
 
Need to get the bossman to make a patch to sort it out. Having the exact same issue. It's a pain in the ass when im trying to do a light lager requiring a mash temp lover than 146.84F/63.8C . Being in AU im degC, if found that the issue is evident at below anything below 63.8C.
 
Hi,
  The adjustment is only applied in a limited range for which I had data for.  Outside of that I don't apply the adjustment because I had no experimental data to support it.  I'll make a note to fix this so it at least remains a constant adjustment outside the range.

All the way down to 62c if possible, a few aussie lagers call for a 62c mash temp. Thanks Brad, really appreciated!!  :)
