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

Target Volume (Gal): 12.68      
Estimated OG: 1.043 Plato: 10.82

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 11.76      
Estimated OG: 1.047 Plato: 11.63

Post-Boil Targets:
Target Volume (Gal): 10.00      
Estimated OG: 1.055 Plato: 13.59

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 13.50      
Recorded OG: 1.046 Plato: 11.54

At 100 percent extraction from the maximum mash potential:
