I didn't notice it until 3.9.1 but the time remaining shown on the LCD is about 10 minutes off.  When it shows 00 time remaining, it still has about 10 minutes more before finishing.  How is this time calculated and is there a setting that I need to change to calibrate this?

These are all just calculated times and depend on many factors, both software and hardware (firmware). The values never match 100% with the actual printing time. This is similar to the calculated times for CNC machining centers.
The Slicer Software writes the time marks into the gcode and displays them on the LCD. If you are working with Octoprint, there is a plugin that allows you to influence the time calculations, but even with this, a 100% match is not possible.
I think the quality of the print is more important, less a deviating print time.

Time remaining comes from the slicer. Are you using the 2.3.0-alpha2 Prusaslicer? It has a known bug that is fixed in alpha3.
