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

Target Volume (Gal): 8.91      
Estimated OG: 1.042 Plato: 10.40

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 21.00      
Estimated OG: 1.018 Plato: 4.50

Post-Boil Targets:
Target Volume (Gal): 6.00      
Estimated OG: 1.062 Plato: 15.17

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 6.00      
Recorded OG: 1.062 Plato: 15.17

At 100 percent extraction from the maximum mash potential:
Total Points: 88.38
