I think you are using < 3.1.0 - in which case the throughput is the 
current instantaneous rate, and the absolute counts are for all 
currently open channels (so they can go backward when a channel is closed).

In 3.1.0 this was rewritten. The absolute counts are now for all time 
(well, since the statistics database started) and you can specify 
sample_age and sample_incr parameters to get historical data - see
