I suppose so... {grin}

On a related topic, maybe you missed my post of the code for extracting
the trendline data to a worksheet. Or, maybe you didn't but have been
busy. In any case, the link:

Since the OP is comparing LINEST with the chart trendline, he must have
already plotted the data. On the assumption that he actually looked at
the plot that he produced, I can only assume that he is interested in
the numerics of the fitting process, not the quality (or lack thereof)
of this particular fit.

horizontal line or, with the application of a fair dose of imagination,
a slight downward sloping trend.
