I would like to get some better understanding about the watering level calculation. I though it was working properly since latest updates, but I start to have doubts again.
Those days in Europe we experience strong heat wave. Temperatures are breaking records (both during day and at night). Weather forecast doesn’t report any rain forecast for the next 7 days.
Still, despite these conditions, the watering % doesn’t go above 80-85%, even though all parameters seem to be far beyond the “normal” setting for the Zimmerman method. Before the recent methodology changes, in such conditions we would have had watering level >100% I think.
Has the reference changed in a way that the level will never go higher than 100% ? This is important as it would mean we need to adjust other parameters (such as standard stations run time) to get desired output.
On the other hand, if there is a particular pattern in the way the data is different from true data (for example, temperature is always 10 degrees below what it should be) you can adjust the weather parameter baseline (in weather options) to counteract that (e.g. by lowering the temperature baseline from 70 to 60 or something like that).
