Also, there have been times that the icon for the challenge patch was reworked. The first time they had a major rework of the design they "retired" ALL of the old design ones, and then re-"awarded" the new ones. Effectively, this doubled the number of challenge patches earned for many users.

I would bet that Greg Boyle had a lot of challenge patches before the redesign, and many of those "doubled up."
