Hey! I'll help you out.
Here's the user manual for the Anova Precision Cooker.
Here's the Anova Precision Cooker Quick Start Guide.
If you happen to have the Nano, I'll link the help desk for it here.
I am not sure if you've seen this recipe already, but here's one that might help.
Also please note, when it comes to sous vide, it's about how thick the food is, not weight. This is probably why you can't find a per pound guide. But if you let us know in the community what you want to cook, how thick the food is, what kind of doneness you want, and any other relevant details for your cook, we can totally help you navigate through it.
Have you seen the time and temperature guide? I suggest taking a peek at it.
The Anova will maintain its temperature as long as it's running. Even when you get an alert that your cook is done, the cooker will not turn off - unless you actively pause it yourself.
Hope this info helps! Feel free to ask all the questions!
