Beautiful day in Colorado to brew...
Based on boiling 12.00 gallonsliters at 1.054 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.058. You wanted an OG of 1.060. It looks like it will be under.
Fermentation completed. Fermented at around 72 degrees. Took Final Gravity and it attenuated down to 1.004 (7.35% ABV). Letting it settle out and clear for a couple of days in a cooler closet that is around 65 degrees.
