I'm not familiar to «delay» in vensim and how to use it. I need one for one of my variables, average daily gain (ADG), which is, in my model, the gain in kg per day for a pig. To be able to create this variable, I need a delay, because I need to compare two bodyweights (Time step = 1 day). For example, on day 20, the pig weights 20 kg and, on day 21, it weights 21 kg. So, the ADG is 1 kg per day. Also, should I use a fixed delay or another type of delay would be more appropriate?
Thanks for your help!
