Rounding may account for some of the discrepancy, but it does seem odd that the final few intermediates are 9s apart whereas the totals are about 6s apart.

The throughput is samples/time so if the times are different the throughput will also be different. > Could you please explain me how to read those results? The '+' lines are current interval only and the '=' are cumulative. The output is intended as a guide to how the test is progressing, not for formal reporting. > Thank you very much for you support and congratulation for your job > Best regards > Sebastiano > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] > For additional commands, e-mail: [email protected] > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
