rpietila - where is that trendline now?
Wrong thread. And 34 celcius too tired to think. It is somewhere between -0.4...-0.5 currently.
But is the trendline itself still holding strong or do you need to make some adjustments because the trend proved to be too far off?
SlipperySlope is using a trendline with fixed slope. My trendline is calculated daily using all available data.
Thus, SS is making assumptions. I am not.
Got a ressource or dynamic plot for your trendline? I only know about an image of the graph from November 2013
