With sparge water, mash water, additional infusions, vessel losses, top-up
water and evaporation rate recorded in the Water Needed Calculator:

Target Volume (Gal): 6.01      
Estimated OG: 1.086 Plato: 20.70

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 11.76      
Estimated OG: 1.044 Plato: 10.96

Post-Boil Targets:
Target Volume (Gal): 10.00      
Estimated OG: 1.052 Plato: 12.81

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 10.00      
Recorded OG: 1.044 Plato: 10.96

At 100 percent extraction from the maximum mash potential:
