Well, sort of. Unless you were to do something like add sugar after the
mash.

Projected points are calculated based on the total theoretical maximum
amount of sugars available at the end of the mash. If you add sugar after
that point, your brewhouse efficiency will be larger than your extract
efficiency.

I would need to either track two separate maximums (mash and postboil) or I
would have to check to see if there non-mashed sugars available and add
those into the brewhouse calculations.

This isn't a new bug, by the way. My calculations have always had this
problem. I almost never add sugar into my wort, and haven't really gotten
around to fixing it. Open a bug and I will get this fix into the next
release.
