Attenuation Issues

[PK]

So, all my own fault in the end it's looking like. The opportunity came up in work for some industrial temperature calibrations so I got to check and it turns out my 'calibrated' thermometer I bought was a good way off. I've done the Brewzilla with the adjustments since (only calibrated the high and low between 60 and 76 using this information) and I've seen 84% with LAX and 77% with Hoppin Pils since.

Wow, it must have been a good way off. Was the brewzilla good to the corrected thermometer, or was that slightly out too, compounding the issue?

Out in the same direction so it was even more off than I thought. Though in reality only off by the amount the thermometer was (1.8C) as I was compensating the temp on the display to the thermometer.
