Steve,

The first could have been a left-over from the night before, so they bit into someone's bid or sell. The second is part of a larger transaction. The third, part of it was taken, and the buyer or seller had to wait for the rest to be taken at a later time. It all fits in from what I can see. You can see then that the 3 drags on in later trades (as the full trade minus 3).

Cheers
