Hello Damien Mazzone,

Thank you for sharing these valuable insights! You’re absolutely right, using LINEST with an Excel Table is a great way to make the regression coefficients update automatically when new data is added. It really streamlines the workflow and keeps the model dynamic.

FORECAST.LINEAR is indeed another handy option for quickly generating predictions without manually building the regression equation, though, as you mentioned, it’s important to confirm that a linear model is appropriate before applying it, and to be cautious with extrapolation beyond the data range.

Your suggestions add a nice layer of automation to the process, thanks again for contributing!
