In the run up to WW I, gravities dipped a little in reaction to tax increases. Falling by a couple of degrees. There was a corresponding small decrease in the alcohol content. It should be borne in mind that, at the time of sale, the ABV would have been higher as the FG given here is the racking gravity, before secondary fermentation.
The drop in hopping was even more pronounces, averaging around 12%. However, if you look at the rates for just before WW I, the difference is even greater. The fall in the Whitbread version between 1895 and 1914 was a full 25%. Such a large change must have had an impact on the character of the beer.
As in the earlier period, the FG at time of sale would have been lower than the racking gravity listed in the brewing records and my table. I would have expected all of the examples to hit at least 80% apparent attenuation.
