Multiple cards, wrong recent readings

Thanks for the great script!
The script is reporting:
Recent Plotting speed ....................... 7.96 MiB/s
with a 4070ti super at 4.0MB/s and  a 3080 at 2.5MB/s
I plot both to the same directory on a xubuntu 23.10 machine. 
The average might be correct, but I installed one card later so I can test that for the next node.
