BrainFried,
Did you notice any bleeding when those came off? If you did not, then, IMO you didn't lose any grafts at all. Bleeding is usually the tell tale sign of a lost graft. And keep in mind, the bleeding should be pretty significant.
Judging by your recipient site at day 6, it looks like you've been incredibly gentle with your washing of the recipient area...that is causing a lot of prominent scabbing to occur. As you begin to get more comfortable with your washing habits, you will probably start to see more of these massive scab/hair globs coming off.
Again, if there was no bleeding, I think you are all set. Rest easy and happy growing to you bud.
