My experiences with 05 are that it finishes a lot dryer than I expect. I have gotten anywhere from 79% to 82% ADF with it, even on high gravity beers. My last batch with it was a 1.098 double brown that 2 re-hydrated packs took from that 1.098 down to 1.020, 78% ADF, and IPAs with it have run up into 82%. This does not say yours were not finished, just that it seems to outperform software and manufacturer expectations every time I use it. I have not experienced over carbing that I could attribute to the yeast itself, just improper weights and volume measurements on my part
