[GPS_Standard] Question about averaging mechanism

[Bob Stewart]

In Summing Mode (haven't looked at voting) I see that the current average is discarded and zeroed when a sampling session ends.  Could someone explain the reasoning behind this to me?  Essentially I'm trying to figure out why each session starts a new averaging count, rather than just applying a change to the DAC and leaving the averaging to run continuously.  I could understand this if there was a coarse correction, but not for a fine correction.
