Top Cumulative Score

Update the output cell to display the highest cumulative score achieved by any player across all rounds based on the table in columns D:F. The specific player does not need to be reported, only the top cumulative score. See Examples

Your solution should use cell references so it updates automatically if the input cells change values.
