This is me theorizing, but maybe there's a discrepancy based on what brand of malt you're using. Each company must be using a slightly different technique and a different source of malt....so I can see why there wouldn't be just one solid number. It's more an average.
On Tap: Barleywine, Coffee Oatmeal Imperial Stout (big big beer)
Fermenting: Double Simcoe IPA
On the Bench: Racer 5 IPA
