Brewers get a low reading if they get more of the top off water than the wort, conversely they get a higher number if they grabbed more of the extract than the top off water in their sample.
I agree with this phenomena. I had this happen on my first batch, and thought better and as Revvy said, the proof was in the pudding. It all did its thing and I had a strong porter as I had hoped for. I would say don't sweat it, you probably took a poor reading.
Man,... That's a lotta hooch!

Revvy and Nurmey. thanks

Thats the answer. I took the reading (bottom sample) immediately after topping with water. Actually, I have been brewing for a while, just never came across this before. I usually dont take a starting gravity. But took one for this since it was an imperial stout.
