So now I'm really confused. I thought as needed was going through a similar calculation and estimating when it was dry enough that it needed water again.
If it is then it is in the background and different and there is no visual representation then?
Also does as needed then use all the data from the zone setup?
I keep reading about 12 months of historical data but that completely baffles me, what does historical have to do with evaporation this week when it's a record high, or a record low, or rainfall etc. I can't for the life of me figure out why the last 12 months matters at all?
I think I'm missing some key concepts on as needed and it now appears to be a huge step back from flex, maybe.
