Looks like a seller has instructed a broker to dribble them out, possibly to minimise the impact on the price, or just get a reasonable average price. Most of the day, every 12 minutes 300-600 shares hit the buyers bid. Why bother (total of ~15,000 shares at that trickle rate), unless also dropped some bigger parcels when the buyers allowed.
Who would be so polite/patient, maybe the Griffith's Estate executor?

Someone was "sure desperate to sell" that last $115 parcel, knocking us down another 2.2% in the process......
