optional the maximum utilization value. Defaults to4.15
. From How to Brew: "This number may be adjusted to customize the curves to your own system. If you feel that you are having a very vigorous boil or generally get more utilization out of a given boil time for whatever reason, you can reduce the number a small amount to 4 or 3.9. Likewise if you think that you are getting less, then you can increase it by 1 or 2 tenths."
