I experience the efficiency drop with big beers too. I brewed an Imperial Hazelnut Porter last Monday. Normally I hit 70-75% every time. My target gravity was 1.080-1.085. Knowing that my efficiency suffers at that level, I left the recipe at my default 70% efficiency, but upped my grain bill to reflect 1.090 for a projected OG. I figured that I might have a freakish accident and actually hit 70% but that I could live with 1.090. Well, efficiency did suffer, just over 60%, but I did hit my original target of 1.085.

When I brew something around 1.050, I hit around 80-85%. Most of my beers are in the 1.060-1.065 range and I hit 70-75% on those. My bigger beers generally run in the 60-65% range. So I guess if I charted these I would get a big X too.

I guess so 8)

Keep in mind, that this will obviously vary by batch size, MLT type/size, probably the manifold/false bottom type, and sparge method.
