I've been fleshing out the settings editor for the next version of Typica lately and have made a change to how that handles batch size limits. That was originally introduced as an optional feature with the default to not limit things at all. Going forward that feature is always enabled, but the default limits are 0 (because negative batch sizes are not possible in this universe) and 1000 pounds (anybody trying to use this with a 7 bag or larger roaster may need to change the setting).
The feature is mainly to catch data entry errors and should be set conservatively based on whatever the actual machine is, but if you don't care about that the defaults won't get in the way for almost everybody. There is a limit to how high you can set the limit, but it's about 4x global production (even more if you set the unit to Kg) which I don't anticipate anybody coming anywhere close to doing. Limits can be expressed in Lb/Kg/g depending on what makes sense for the user/machine.
