... absolutely correct to a “T”, as far as I’m concerned.
Keep your messages coming, Tracker, you have good input. The expressions "To a T" and "Screwed Up to a T" go back to the old technician grades during World War II. Back then it was a stripes-for-skills kind of thing, which offended the old-school NCOs. My Dad was an E3 technician, two stripes with a T, and later a E4 tech, three stripes and a T. As a courtesy they were called corporal and sergeant, and those ranks were the origin of the later Specialist grades.
