what could cause this data difference at subscriber and publisher ends.
Min/Max aggregation mode is selected. We tried changing this mode to SimpleAverage; the results were slightly better but not identical.

The sample frequency is multiple data points per second, so I'm going to go out on limb here and suggest that this discongruity is related to transmission time.

Consider this representation of the data:

The data actually lines up pretty well, but it is 3 to 5 seconds out of sync.
