43.2 * 6.5/5 = 56.2...

49 / .75 = 65.3

56/65 = .86...

That's 86% efficiency. That's unbelievable, as in, I don't believe it.

But it's how the math worked out. What was supposed to be a modest gravity pale ale is on the verge of being an IPA. I'm going to adjust the dose of bittering hops just a bit, to .6 oz.

I'm guessing I got a point or two from the base malt, which pro mash assumed to be 1.036 potential extract. It could have been as high as 1.038, I think.
