On the contrary, zoom back so you can see November 25th when they announced giveaway day. Better yet, pull back to "max". Would one not expect a lull afterward? It was announced far enough in advance that people could choose to get their upcoming stuff on giveaway day. Maybe some of the free-getters were new customers who might repeat, but the value was in the press on November 25th.
