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): 11.85      
Estimated OG: 1.045 Plato: 11.26

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 13.56      
Estimated OG: 1.040 Plato: 9.88

Post-Boil Targets:
Target Volume (Gal): 10.00      
Estimated OG: 1.054 Plato: 13.24

Recorded Actuals - Measurement Taken In Ferementer:
Recorded Volume (Gal): 10.00      
+Losses (Gal): 0.48      
Total Volume (Gal): 10.48      
Recorded OG: 1.048 Plato: 11.92

At 100 percent extraction from the maximum mash potential:
Total Points: 71.50
Points From Mash: 71.50
Points From Extract/Sugar: 0.00

With the recipe efficiency setting, you should have achieved:
Total Points: 53.63
Points From Mash: 53.63
Points From Extract/Sugar: 0.00

Actuals achieved were:
Actual Points From Mash: 50.36
Actual Mash System Efficiency: 70 %
