And, yes, the quantity of data to fiddle with put me off, too. At this rate my series on Drybrough's beer will last until judgement day. Or maybe a little longer. We may have devolved back into worms by the time I'm done.
Some general remarks to start with. The recipes for all three beers are generally similar: 80% pale malt, 20% sugar (or sugar and flaked maize). Which is pretty typical for all Pale Ales of the period. It's a point I've made many time before, but I'll repeat it again: crystal malt in Pale Ales was almost unknown before WW I and not common until after WW II.
Note that pale malt (or the closely related PA malt) is the only malt used in any of the beers. Though it's also clear that Drybrough's and Fuller's beers have been darkened with some sort of sugar. I suspect that Whitbread were colour adjusting with caramel at racking time. That's what they did after the war to hit their colour standard.
Which begs the question, when did they stop trying to make Pale Ale as pale as possible and start deliberately darkening it? Looking over my tables, it seems Fuller's started adding caramel to AK in 1902. Barclay Perkins started adding caramel to their Ordinary Bitter, XLK, just before the outbreak of WW I. Interesting, that. I wonder what the reason was? Because it's before the big drop in gravity, which would have been an obvious cause.
Whitbread were the most conservative, or consistent, depending on how you look at. As the "other sugar" is almost certainly No. 1 invert, there's almost no change at all. Except that in 1917 and 1918 the percentage of sugar fell, because it was rationed:
"About this [October 1917] time sugar became rationed and brewers were only allowed to use 25 per cent, of the amount they used in 1915."The effect of sugar rationing is also apparent in the grists of Drybrough and Fuller's. In October 1917 the percentage of sugar in Drybrough's PI grist fell from 9% to 5%. At Fuller's the reduction was even more dramatic, from 10-15% to just over 2%.
Journal of the Institute of Brewing Volume 46, Issue 4, August 1940, page 273.
As a result of the lowering of the amount of sugar used, the malt percentage in the grist went over 90% at all three breweries. Ironic, that a side-effect of the war should be to increase the malt content of beer. Though it is logical. Barley has limited use in feeding humans, whereas the opposite is true of sugar.
British brewers' love of sugar is demonstrated by the fact that when it became available again, the percentage used went back up to pre-war level, or even a little higher.
Drybrough's use of Poperinge hops throughout the war is a bit surprising. Especially as they weren't all from the pre-war crop. In 1918 they were using ones from the 1916 harvest. While Poperinge was in the corner of Belgium unoccupied by the Germans, it was just behind the front lines and subject to shelling and other disruption.
Fuller's used Poperinge hops, too, but only at the start of the war and after its end. The main attraction of this type of hops was their price. They were amongst the cheapest available. For most of the war, like Whitbread, Fuller's used English hops, mostly from Kent. There were plenty to go around. The reduction in demand for hops caused by falling gravities produced a glut of English hops. Only government intervention stopped most farmers going bust.

I have always found Drybrough’s “faceless man” logo slightly creepy.
