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

Target Volume (Gal): 13.60      
Estimated OG: 1.038 Plato: 9.56

Raw Pre-Boil Targets - only targeted volume/gravity and evaporation
rate taken into account:
Target Volume (Gal): 12.31      
Estimated OG: 1.042 Plato: 10.52

Post-Boil Targets:
Target Volume (Gal): 10.00      
Estimated OG: 1.052 Plato: 12.85

Recorded Actuals - Measurement Taken In Kettle:
Recorded Volume (Gal): 12.50      
Recorded OG: 1.050 Plato: 12.31

At 100 percent extraction from the maximum mash potential:
Total Points: 74.20

Mash Notes
Was trying to hit 140', but thermometer malfunctioned. Hit 146 for the beta rest, which should be ok for high fermentability. Proceeding with 158 alpha rest.
