Every tech would prefer to do a job that had accurate previous notes attached. A tech complaining that it takes too much time to take measurements? BS. They don't take notes because they're lazy, and because you let them get away with it using that cheap excuse. That's like guys saying they don't mention stain protectant because it takes too much time to apply. A laser tape that does area calculations runs between $25 and $65 and can help even the most inept tech get with the program. I'd suggest giving one to any tech that can do their paperwork correctly for two weeks. That should be enough time to make doing things correctly the new habit.
