The malt you get can also make a difference. Five pounds of my previous pale ale malt got me 1.040 in a three gallon batch. I got a bag of Crisp #19 floor malted maris otter and started getting 1.050.
Absolutely. I entered a British barleywine into a compitition and got so-so scores: "Too hoppy for style ". A year later it got the highest score I've ever received and second in best of show.
