Thank you for this guide.
I have a question regarding CO2 extract example you explain in the article :
"For simplicity you can use the approximate density of 1 gram for 1 ml of hop extract. So adding 1 ml or 1 gram of 65% alpha extract boiled for 60 minutes to a 1.050 OG beer gives around 10 IBUs depending on your exact equipment losses and equation used."

However, when repeting it in beersmith, I'm getting 7.7 IBU. You said that equipment losses and equation can affect this estimation. Could you be more specific about what parameters could affect this calculation ?
Thanks

I'm having the same issue. I created a 5 gallon recipe, 1.050 og, and I even eliminated all losses from the equipment profile.  It's still calculating about 8 IBU per ml instead of 10, using the tinseth formula.
