Batch sparge - 2 times, strike water was a bit too hot so decided to mash at 164...didn't want to wait for mash to cool down
Based on boiling 6.50 gallonsliters at 1.047 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.054. You wanted an OG of 1.055. It looks like it will be under.
