(Include any important notes from brew day until tasting)
This was the biggest brew I have brewed on my AG system, plus I was using a new brew kettle. My 10 gallon mash tun was filled nearly to the top, and unfortunately, after filling and dough in, temp was low, so I had to add some boiled water to get it up to 153 F, when I was targeting 154 F.
Also, I ended up with 8.8 to 8.9 gallons of runoff when I was expecting 8.2, so I had to boil a little longer to evaporate some of the excess. This has probably happened to me several times before and because I didn't have a sight glass, I didn't know.

Gravity Estimates
Based on boiling 8.20gallonsliters at 1.042 for 90 minutes, this will decrease your wort by 1.50gallonsliters, bringing your after boil OG to 1.050.
You wanted an OG of 1.076. It looks like it will be under.
