It looks as if the system aims to 'counter' the detected setting error over
one poll interval. That would make sense for a system whilst left on since
each subsequent correction of the rate is to the 'soft' clock which has
already been given the earlier corrections. To test this, you/others could
experiment with different poll intervals.
It looks like your hard clock drifted by about 0.378 sec in about 226 mins.
That seems consistent with what I get with my machine's hardware clock
which drifts by a second or two per day.
