Alex's beer. Stirred mash after 30 minutes. Temp stayed constant. Secondary 1/31 1.018
Based on boiling 7.00 gallonsliters at 1.061 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.070. You were planning on an OG of 1.070 so you are right on track. Nice job!
