Big Beer Question :)

Hey folks i brewed last tuesday Ed Wort's Bee Cave Honey Robust Porter, which ended up giving me a og of 1.080.. It fermented like a beast from hell for a few days and i checked the SG again today and it was @ 1.020.. I was checking my beer calculator and it was saying i had a Apparent Attenuation of 73.7%... I think im going to check the gravity again in a couple days,, but does this sound like as low as the SG will drop? I have never made a beer with such a high OG b4.. Any comments i would appreciate it ... ill also attach a pic of the ferment from hell haha

even ed says he only gets it to 1.020-1.022

straight from his post about it: Mine finishes around 1.020-1.022 because of the malto dextrin

Sweet... Ill move it to the secondary soon then!

I think you fermented that way too warm.
