Reduce sampling rate to every 10 seconds, don't truncate counter data at 8 bits, measure flow rate once rather than trying to explicitly integrate over the course of an entire event.
Poll every 10 seconds.
Comment to de-mystify the magic timestamp offset number.
Merge branch 'feature-report-log' into feature-poll-flow-rate
Don't forget about additional comm modules if retrying fails for one.  Also implement formatted log composition.
Improve logging to conserve log entries.
