next time cool the wort then whirlpool it like mad then let it sit covered for 10 minutes. this should mix your wort and extract good and give you a more accurate reading.
Thank you very much for the advice. I'm a rookie so I'll keep that in mind for next time!
The recipe was as follows:
5.5 lbs Munton Medium Malt Extract
0.6 lb Roasted Barley
0.6 lb Chocolate Malt
1.0 lb Extra Dark Crystal Malt
1 lb Lactose
300 ml (roughly 10oz) Molasses
60 grams (roughly 2 oz) Northern Brewer --60 minutes
30 grams (roughly 1 oz) Fuggles -- 30 minutes
