Vehicle Height/Suspension Measurement Input...Factory Vs. Now

I wanted to know how much my 250k+ miles 2003 DC TRD Off-Road suspension has sagged. I bought the truck in 2007 with about 66k miles from the original owner. Doubtful any mods done to it by him. It didn't even have a receiver hitch. Anyways, I found some specs posted by another member and measured.

According to the Toyota spec sheet:
Front Height...Measure (A) ground clearance of spindle center and subtract (B) ground clearance of front adjusting cam bolt center. My (A) measurement (as best I could tell) is 14.25" and (B) measurement (as best I could tell) is 11.125" resulting in a difference of 3.125". The factory spec says 2.72"! Is it possible the front is 0.40" TALLER than factory at this point?

Rear Height...Measure (C) ground clearance of rear axle shaft center and subtract (D) ground clearance of leaf spring front hanger pin bolt center. My (C) measurement (as best I could tell) is 14.00" and (D) measurement (as best I could tell) is 14.50" resulting in a difference of -0.50". The factory spec says -0.67"! Again, is it possible the rear has only sagged 0.17" from factory at this point?

Maybe I wasn't measuring correctly? I don't know. It is pretty straightforward though.
