Machines are much better at precise measurements than people. I'm not
sure I could tell the difference between 200 OVC and 700 OVC by eye, and
I'm sure I couldn't between 1000 and 2000.

I don't claim to be expert at that, either, but when the previous a/c
reported breaking out at minimums, 200 feet, the observer continued to
report 700 feet.
