This may not be a good representation of the actual grain bill. For example, 
oats were  often substituted 2:1 for wheat in receipts by regulation when 
using a sack measure, yet the quarter measure had one-to-one. From my 
reading of 14 & 15th century English brewing regulations, I believe that the 
weight interpretation is the correct one for the Domesday receipt.

The two resulting grain bills are radically different and will produce two 
different beers.
