Eyeballing an old version of the errata document (November 1, 2014), and ALSO taking into account the adjustments made to personal combat, I see:
Up to page 200 (9 pages errata) were about 50% done.
Personal combat (3 pages) is essentially done.
GunMaker, ArmorMaker, and VehicleMaker (3 pages) were largely not yet addressed.
Starship design (3 pages) were 50% addressed.
How ship systems work and ship combat (2 pages) were perhaps 10% addressed.
Worlds, star systems, trade and commerce (4 pages) were maybe 25% addressed.
Technology, computers, consoles, controllers (half page) were unaddressed.
Psionics (1 page) unaddressed.
Sophonts, BeastMaker, ThingMaker, and Equipment (4 pages), 25% addressed.
These are very rough estimates, and they're working off of an old errata document PLUS the personal combat updates.
Errata correction as of 11/2014 is, very approximately, 40% done.
