Shut up about Barclay Perkins - Scottish Stout 1947 - 2004

We're finally there. At the last part of my look at Scottish Stout. Through numbers. What better way is there to look at beer?
There are so many beers in this table - no surprise as it runs from WW II to the present - I've used a little spreadsheet maths to help me out. These are the averages it spat out:
OG 1017.3, FG 1040.9, ABV 3.06%, apparent attenuation 57.00%.
Of the 85 beers in the table (there are actually 86 beers in the table, but I have no FG for one), 27 had less than 50% attenuation. Here are the figures in more detail:

Only 13 beers had attenuation of over 70%, which is about the level I would call normal. That's just 15% of the total.
In terms of OG, the results are even more conclusive. More than 90% of the beers are below 1050º. 60% are below 1040º. Here's it all in convenient table form:
