Too much oat high FG???

[dudybrew]

Hey guys I need your opinions.
I brewed 10 days ago a Dry Stout. OG 1053.
Turns out I decided to add extra oat to my recipe because I wanted extra dense foam on it, so I added 700 grams of flaked oat to my 20L batch. And the recipe I bought had already 140 grams, summing to 840 grams of oat which I did a protein rest at 60*C.
Two days after brewing and putting it to ferment the beer was 1034(8,5 brix), on the refratometer, I did the conversion and it´s like 1022.
Yesterday i measured on the densimeter and it shows 1020, and the same thing on the refratometer.
I tasted it and it´s very dry, doesnt feel sweet.
I am wondering if the extra oat made the FG get so high, but still converting a good deal of the sugar in it?
Then how could I calculate the ABV?
I dont know I am a bit confused, I am kinda newbie.
Thanks for the insights... ta...

Abv is 4.4%

thanks bribo...
do you thing the extra oat explains the high FG?
and if the ABV was meant to be 5,3 do you thing there wasnt a good attenuation?

You probably have some unfermentable sugars from the oats which should explain a higher final gravity.

These sugars don't necessarily give the beer a sweeter taste...just more body and mouth feel.

Should I put it to secondary and then in the fridge at 6*C for a week? will it carbonate ok after this?

Let it sit in the primary for 3-4 weeks...the prime and bottle as normal. it'll be fine
