I've not quite yet run all the data I have through all of these calculators. In particular, I have yet to look at all the data you sent a while back. Time to do it, I guess. I will say, though, that I have run your batch 128 (Boont Amber) through MpH 4.2 and I get a difference of 0.01 [with a correction factor of 0.65 (which on average appears to give the most accurate results)], while you calculated 0.05. Obviously, we entered at least one thing differently, but this does not necessarily imply user error on either your part or my part. It likely is due to a difference in choice of a malt of two to use for the calculations. Perhaps you could email me a few copies of MpH with several of your beers entered? I would like to track down the difference, in case there is something systematic.
