Efficiency Specifics
Recipe Efficiency Setting: 75 %

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

Target Volume (Gal): 2.47      
Estimated OG: 1.216 Plato: 47.10

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 12.22      
Estimated OG: 1.044 Plato: 10.88

Post-Boil Targets:
Target Volume (Gal): 11.00      
Estimated OG: 1.049 Plato: 12.04

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 11.00      
Recorded OG: 1.048 Plato: 12.00

At 100 percent extraction from the maximum mash potential:
Total Points: 64.73
Points From Mash: 64.73
Points From Extract/Sugar: 0.00

With the recipe efficiency setting, you should have achieved:
Total Points: 48.55
Points From Mash: 48.55
Points From Extract/Sugar: 0.00

Actuals achieved were:
Actual Points From Mash: 48.37
Actual Mash System Efficiency: 75 %
